On LADA cars LARGUS are installed gasoline, in-line, 4-cylinder 8th and 16th valve engines with a working volume of 1.6 liters. with 2 or 4 valves per cylinder.
Location of identification plates with numbers on the engine. The ratio of the installed engines and gearboxes in the complete sets, see.
Until mid-2016, the car was equipped with Renault K7M (8-cl) and K4M (16-cl) engines.
Since 2016, their modern counterparts manufactured by AvtoVAZ have been installed. Accordingly, the K7M was replaced by an engine VAZ-11189, and K4M was replaced by VAZ-21129... The engines are distinguished by a lightweight ShPG, an automatic timing belt tensioner, a metal cylinder head gasket, a body kit and supports.
From 2019 to Lada largus CNG (with LPG) dual-fuel engines 21129 CNG are installed.
The location of the power unit is front, transverse.
In accordance with the vehicle configuration, there are several options for installing auxiliary equipment on the engines:
Steering car without power steering;
A car with a steering system without power-assisted air conditioning;
Vehicle with hydraulic power steering;
Vehicle with hydraulic power steering and air conditioning.
The main parameters and characteristics of the motors are given in tables 1 and 2.

ENGINE 1,6 (8V)
K7M engine gasoline, four-stroke, four-cylinder, in-line, eight-valve, with an overhead camshaft. The order of operation of the cylinders: 1-3-4-2, counting from the flywheel. Power supply system - distributed fuel injection (Euro 4 toxicity standards).
Engine (front view): 1 - air conditioning compressor; 2 - drive belt; 3 - generator; 4 - power steering pump; 5 - oil dipstick; 6 - cylinder head cover; 7 - ignition coil; 8 - tips of BB wires; 9 - cylinder head; 10 - thermostat housing; 11 - exhaust manifold; 12 - water pump pipe; 13 - sensor insufficient pressure oils; 14 - plug; 15 - flywheel; 16 - cylinder block; 17 - oil pan; 18 - oil filter
The engine with the gearbox and clutch form the power unit - a single unit fixed in the engine compartment on three elastic rubber-metal bearings. The right support is attached to the bracket on the top cover of the timing drive, and the left and rear support to the gearbox housing. On the front of the engine (in the direction of vehicle movement) there are: an exhaust manifold, an oil filter, an oil pressure warning sensor, a coolant pump inlet pipe, spark plugs, a generator, a power steering pump, an air conditioning compressor.
Power unit assembly (rear view): 1 - gearbox; 2 - crankshaft sensor; 3 - inlet pipeline; 4 - sensor of absolute air pressure in the intake manifold; 5 - inlet air t sensor; 6 - throttle assembly; 7 - idle speed regulator; 8 - oil filler cap; 9 - fuel rail; 10 - oil dipstick; 11 -GBTs; 12 - cylinder block; 13 - drive belt; 14 - oil pan; 15 - knock sensor; 16 - support bracket of the inlet pipeline; 17 - starter; 18 - speed sensor
On the rear of the engine are: an intake manifold with absolute pressure and intake air temperature sensors, a throttle assembly with a throttle position sensor and an idle speed regulator, a fuel rail with injectors, a knock sensor, a starter, an oil level indicator.
On the right - the coolant pump, the drive of the gas distribution mechanism and the coolant pump (toothed belt), the drive auxiliary units(poly V-belt).
On the left are: flywheel, thermostat, crankshaft position sensor, coolant temperature sensor.
Top - ignition coil, oil filler neck.
The engine block is cast from cast iron, the cylinders are bored directly into the block.
In the lower part of the cylinder block there are five crankshaft main bearing supports with removable covers, which are attached to the block with special bolts. The holes in the cylinder block for the bearings are machined with the covers installed, therefore the covers are not interchangeable and are marked on the outer surface to distinguish them (covers are counted from the flywheel side).
On the end surfaces of the middle support, sockets are made for thrust half rings that prevent axial movement of the crankshaft. 
Engine (right side view): 1 - drive belt; 2 - pulley drive belt; 3 - oil dipstick tube; 4 - support bracket of the inlet pipeline; 5 - lower timing case cover; 6 - inlet pipeline; 7 - throttle assembly; 8 - upper timing case cover; 9 - oil filler cap; 10 - ignition coil; 11 - power steering pump pulley; 12 - generator; 13 - support roller of the belt; 14 - belt tension roller; 15 - air conditioner compressor pulley; 16 - sump of the engine crankcase
The liners of the main and connecting rod bearings of the crankshaft are steel, thin-walled, with an anti-friction coating applied to the working surfaces.
Crankshaft with five main journals and four connecting rod journals. The shaft is equipped with four counterweights, made in one piece. Counterweights are made on the continuation of the "cheeks" of the engine crankshaft. Counterweights are designed to balance the forces and moments of inertia arising from the movement of the crank mechanism during engine operation. To supply oil from the main journals to the connecting rods, channels are made in the journals and cheeks of the shaft.
At the front end (toe) of the crankshaft are installed: an oil pump drive sprocket, a timing gear (timing) drive pulley and an accessory drive pulley. The toothed pulley is fixed to the shaft by a protrusion that fits into the groove on the toe of the crankshaft and prevents the pulley from turning.
Similarly, it is fixed on the shaft and the accessory drive pulley.
Engine - left side view: 1 - check point; 2 - air conditioning compressor; 3 - generator; 4 - thermostat; 5 - coolant t sensor; 6 -GBTs; 7 - cylinder head cover; 8 - ignition coil; 9 - oil neck; 10 - fuel rail; 11 - throttle position sensor; 12 - throttle assembly; 13 - inlet pipeline; 14 - air inlet t sensor; 15 - sensor of absolute air pressure in the intake manifold; 16 - cylinder block; 17 - crankshaft position sensor; 18 - speed sensor
Connecting rods - steel, I-section, processed together with caps. The covers are attached to the connecting rods with special bolts and nuts.
Piston pin - steel, tubular section. The pin pressed into the upper connecting rod head rotates freely in the piston bosses.
The piston is made of aluminum alloy. The piston skirt has a complex shape: in the longitudinal section it is barrel-shaped, in the transverse section it is oval. In the upper part of the piston, there are three grooves for the piston rings. Top two piston rings- compression, and the bottom - oil scraper. Compression rings prevent gases from escaping from the cylinder to the crankcase and help transfer heat from the piston to the cylinder. Oil scraper ring removes excess oil from the cylinder walls when the piston moves.
ENGINE 1,6 (16V)
K4M engine gasoline, four-stroke, four-cylinder, in-line, sixteen-valve, with the upper arrangement of two camshafts... The order of operation of the cylinders: 1-3-4-2, counting from the flywheel. The power supply system is distributed fuel injection (Euro 4 toxicity standards). The engine with the gearbox and clutch form the power unit - a single unit fixed in the engine compartment on three elastic rubber-metal bearings. The right support is attached to the upper cover of the timing drive, and the left and rear support to the gearbox housing.
Note: The following information is general knowledge and is not tied to any car brand.
Now, apparently, there is no point in recalling the legends of deep antiquity - all sorts of there steam engines at the dawn of the automotive industry, babbitt liners, gravity and spray lubrication ... Yes, all this once also existed and even drove, but at the initial stage of any activity, difficulties are difficult to avoid. With the growth of scientific and technological progress, the owner of the car no longer needed to have a personal chauffeur with a mechanic diploma and the skills of a car mechanic worked out to the point of automaticity. But all the same, the driver still had to have some understanding of the process, otherwise you will not go far. Once again I pressed the gas when starting the carburetor engine - I filled in the candles: unscrew and ignite or wait until they dry themselves, and time passes ... I forgot to connect the front axle and blocking off the road - I got stuck. Have you forgotten that the second axle must be turned off when driving back onto the asphalt, and the differentials must be released? Save money for replacement transfer case and gearbox.
And now? Everything is controlled by electronics. Need to start the engine? Press at least all the pedals at once - the control unit, through high-precision injectors, will measure out exactly as much fuel as needed, having checked with numerous sensors and a flow meter. The car is a product of the collective mind, and it does not matter where it was made - in Germany or in China, precedents are evident, remember the same Haval. BMW uses the system all-wheel drive from one leading Canadian company? Are we worse? We will buy automatic transmissions from the same Germans, they say, good ones. The engine itself is too lazy to develop, the Austrians suggest, let's take, perhaps - the Volkswagen Group used their services, and everyone was satisfied.
Now, when driving off the asphalt into impassable mud, you don't need to think about anything - the automatics will connect what is needed and lock the free differentials, on some models you don't even need to touch the pedals - the car goes by itself, just turn the steering wheel. If you don't know how to park, an automatic valet will help you, you don't even need to turn the steering wheel. Didn't have time to brake in front of the zebra? It doesn't matter, the car will stop by itself if there are pedestrians at the crossing, it's not for nothing that automakers fight that kind of money for Pre Safe systems. Actually, autopilots are already being tested with might and main, even in our country we have our own developments from the same Yandex, a little more and ...
On this, in fact, the good news is exhausted. Now the news is bad. Not that they are bad for everyone, but rather for some. It is sad that 90% of the population of our country belongs to these "some". The further story is devoted to these motorists. Worldwide practice in relation to road transport is such that the obsolescence of promising technology goes very quickly. The toxicity standards are constantly changing, and the ubiquitous electronics takes over more and more functions. Against this background, the resources of power units of 500,000 - 1,000,000 km and no longer suit anyone. Marketing also does not sleep - programmed aging, non-repairable components and assemblies. On the one hand, it is understandable - in prosperous Germany or the United States, all this is relevant, but in our country, with such a standard of living, such innovations simply knock the ground out from under our feet - with a similar level of auto-mobilization, road network and prosperity, new realities are perceived purely negatively. Few Russian citizens can afford a car for 3-10 million with all these bells and whistles and change it every 3-5 years.
Fortunately, automakers understand that in the world there are not only developed countries like the USA, Germany, Japan, France, etc., but also developing countries like Iran, Nigeria, Angola, Sudan, and now also Russia, so cars, supplied there are often very different from promising technology, and, according to our realities, for the better.
By the way, Eastern Europe is not yet so matured in abundance, and good news often comes from there, supported by the necessary models. Take, for example, a division of the Volkswagen Group, Skoda: a unique situation has developed with it - the Czechs often offer new models with proven old units, well, who else does that? Try to buy Volkswagen passat without turbocharging, direct injection and a preselective box - it will not work. Of the simple models, only Volkswagen polo... If you want prestige and convenience, invest in the latest technologies and programmed aging, which was originally incorporated in all units of new models. In fact, the consumer is invited to pay out of his own pocket for the fact that a prestigious new car will soon fall apart, and it will not be possible to repair or somehow significantly postpone the deadline for death - everything is thought out. The situation from the point of view of logic is the wildest, and they understand this even in wealthy Western Europe, so in some Frankfurt or Dusseldorf it is Skoda that work as a taxi - up to 70% of the entire fleet. It is enough to look out of the airport window in order to be convinced of this. Taxi drivers can be understood - the unkillable atmospheric MPI development) of twenty years ago and the classic automatic transmission will last clearly longer than the promising TSI and DSG, perhaps at times, despite the sparing conditions of European operation.
Mitsubishi once brought its new development GDI, however, having discovered reliability problems, after a few years removed the GDI motors from the European market as a whole - it turned out that there is a lot of sulfur in European gasoline, which the developers did not count on, since Japan has its own GOST standards for impurities. But, unfortunately, not everyone does this. Usually it turns out exactly the opposite.
An icon of marketing style and one of the worst engines in automotive history is the N63 engine from BMW. Actually BMW engines knows how to do, how did it happen that now not only the top-end N63, but also the rest of the modern power units of the concern do not shine with reliability? Yes, everything is simple, it is now accepted, but even against this background, the N63 is unique. The mechanical resource is up to 60,000 km, and it is not a fact that before this time the turbines will have to be changed a couple of times, since they are in the hottest place, however, the entire motor is very overheated. Injectors tend to "pour", leading to a water hammer, in general, the engine consists of almost one problem, which is extremely expensive to eliminate. How did it happen that it stands on the most popular top-end models: "seven", "six", "five", X5, X6? Moreover, it did not even stay within the brand and at one time occupied a place under the hoods of the tinted Range Rover. It's just that the Bavarian marketers got into the very heart of the Target Group - what does it matter to officials, top managers and just very wealthy people who do not count money, to operating costs. For some, the population pays, for others - the firm - the owner of the corporate park, and for the third it is important to stick out their "I", and for this, no money is spared. The term of owning a car is a maximum of a couple of years, then it will simply get bored, and the mileage of such a vehicle is small. In general, at present, you should not focus on premium segment cars, even with low mileage - apart from problems, you are unlikely to get anything. The rest of the promising and, in particular, premium equipment is designed in the same way, so if you do not have the task of constantly spending serious sums on repairs and the purchase of the next car, it is better to turn your gaze the other way.
All this preface is written for a reason. If today we are talking about the health of the engine and its longevity, then the first item on the agenda will, of course, be the choice of the power unit, in order to then simply carry out scheduled maintenance without any repair, replacement of units, ships with warranty departments of dealerships and similar inconveniences that tend to drag on for a very long time, especially in our country.
So let's start with direct injection. Against the background of the Russian economic miracle: when fuel in the wholesale is more expensive than in retail, it is ridiculous to wait for the proper quality from gasoline and diesel fuel, and direct injection is a high-precision thing and does not like it. Of course, modern systems like Di-Motronic and Neo-Di are not as delicate as the ever-memorable GDI, but when buying a car, if possible, you should avoid direct injection, all the more, apart from reliability, spare parts for such systems are many times more expensive. You can't go anywhere with a diesel engine - Common rail now there is no alternative. However, in this case, it is better to study the issue before buying. For example, PSA diesel engines performed well even in Russia, which cannot be said about heavy fuel ICEs from a number of other companies.
Accordingly, it is better to prefer standard distributed injection when it comes to gasoline - Motronic or its Asian counterparts. These systems are still actively used by automakers, and not only in the budget segment. It is better to avoid supercharged internal combustion engines, all the more so beloved by VW Group double supercharged TSI with a turbine and a compressor, high power and tiny volume - you should not expect a decent resource from such small cubic meters, especially if no one will repair it for you. To capitalize on this downsizing miracle is also unlikely to come out - there is neither a margin of safety, nor a place for the introduction of sleeves. By themselves, turbines by now also reduce the service life of the unit, since the boost is good only up to a certain limit - if you remove 360 hp from two liters, as Mercedes-Benz did in its A 450 AMG, you will wait for a decent resource from such an engine funny. In addition, the modern turbines themselves are now the weak link, especially if they are placed closer to the hot catalysts, like some BMW models, and they cost a lot of money.
In general, throwing away everything that is promising and irrelevant for the Russian realities, we get an aspirated engine with distributed injection - this is by far the most tenacious design, and to extend the resource of such an engine, despite all the marketing tricks, the task is quite real.
But, even having found a car with the desired engine in a car dealership, it would be nice to pay attention to another aspect - the "start-stop" system. It's just that its presence is not yet a reason to refuse a purchase, if it is possible to programmatically cut it down forever. And if not? Think for yourself how convenient it will be for you to turn off the automatically activated system every time you start the motor. In developed countries, it may allow saving a little fuel due to the resource of the engine and starter, but in dead Moscow traffic jams, such savings will definitely come out sideways, all the more so the battery under its "start-stop" is 2-3 times more expensive than usual, and in general all electrics have their own, rather expensive.
Quality lubricants and expendable materials for TO - is already the key to success. The sad thing is that now even the automaker is trying to nudge the user into making the wrong choice. For example, when selecting an oil filter for World Engine, the well-known Mitsubishi "aspirated", which was installed on Peugeot, Citroen, Hyundai, Kia, JEEP, Dodge, Fiat, it suddenly turns out that now, in addition to the original filter number, the program also gives a persistent recommendation use oil no thicker than 5W-30, directly in the original JEEP program. This section has never contained such information at all, where did it come from now? And why exactly like that? Indeed, a few years ago, the recommendations were opposite and quite understandable. Has the motor mechanically changed? No. The answer is simple. Excellent performance characteristics, but outdated, according to environmentalists, World Engine with distributed injection with great difficulty fits into modern draconian toxicity standards, and in order to be able to sell cars with similar power units, the automaker has to "press all buttons", including reducing internal resistance by applying a more fluid lubricant. The method is so-so - the classic "aspirated" will definitely not like this, but from the point of view of marketing it is even better: the engine will fail faster - the buyer will buy a new car faster.
So what about engine oil There is only one recommendation: do not use a hot viscosity less than 40, and if you are a fan of turning the engine, it is better not less than 50 at all. We have roughly decided on the viscosity. Now the composition. Now, unfortunately, it is difficult to distinguish hydrocracking oil from synthetic oil at a retail outlet - they are labeled the same way, and special equipment is needed to measure the flash point. But it is worth remembering that hydrocracking oils serve a third less, so when buying inexpensive synthetics, you need to understand that there is a 99% probability of a hydrocracking product in a canister. It is undesirable to take mineral water today, unless, of course, you have a very ancient power unit: it serves even less, besides, its lubricating characteristics depending on temperature are much less stable. Semisynthetics is an average option, it also needs to be changed quite often, and this is logically understandable. Now to the question of the oil change interval. If we proceed from engine hours (namely, all overseas equipment is guided by them), dealer recommendations for mileage should be divided by two. The oil in dead traffic jams ages even faster than on the move, so if you are traveling in a large city, this moment must be taken into account.
The last but also extremely important recommendation is tireless monitoring of the cooling system. There is some mess with the colors of the antifreeze used among the manufacturers of technical fluids, so you need to focus not on the color, but on the composition of the antifreeze. It is necessary to observe the replacement times and drain the coolant from the system as a whole, and not in parts, adding portions of fresh product. A very important point is the condition of the cooling radiator. If it is clogged with dirt, heat exchange is difficult, and now there can be only a few degrees between the temperature of the opening point of the thermostat and the boiling point of the system - everyone is chasing efficiency, and thermodynamics cannot be fooled. So it is also necessary to closely monitor the radiator, preventing the deterioration of heat transfer, in other words, it should be rinsed in a timely manner.
And the last most common advice is to beware of counterfeit products, the number of which is growing at a tremendous pace. If you use "stale" oil, left-hand filters and refuel at suspicious gas stations, "where a whole ruble is cheaper," the reckoning will follow immediately. So it is better not to save money on consumables for maintenance and technical fluids, buying everything at large and trusted retail outlets.

Lada Largus models can be equipped with two types of engine - with 8 or 16 valves. The final price and equipment depends on which engine you prefer to have under the hood of your new car. Let's understand the advantages and disadvantages of each option.
general information
For the first time, the Lada Largus station wagon appeared on sale in 2012. It is produced in two versions - for the carriage of passengers or goods. Motorists are more interested in the passenger version, which, according to the manufacturer's idea, can accommodate 5 or 7 people. When developing this model, special attention was paid to such characteristics as:
- speed;
- comfort of the driver and passengers;
- smooth running.
The engines for this car were manufactured by the Renault concern, each of them is designed for use in the Russian climate. Any engine installed on a Lada Largus car can be used in the following conditions:
- winters;
- off-road;
- sharp temperature fluctuations.
Similar motors are installed on adapted Renault and Nissan models. Regardless of the valve system, the engine on the Lada has a volume of 1.6 liters and an electronically controlled distributed fuel injection system. The motors are paired with a manual transmission, since the manufacturer decided not to use the automatic transmission on the Lada Largus.
Another feature from the domestic manufacturer was the use of only gasoline units operating on the AI-95 brand. AvtoVAZ specialists explained this by the fact that, despite the lower cost of diesel fuel, the assembly and maintenance of diesel engines will cost more. Minor fuel savings are disadvantageous to both producers and consumers. In terms of environmental friendliness, the joint production with Renault-Nissan allowed Largus to be tested for compliance with the Euro-4 standard.
The manufacturer has installed a resource of 160 thousand kilometers on any engine of this car. After this mark, you may need overhaul, but with proper care, Lada Largus can easily travel much longer without stopping. Moreover, in the passports for each engine, different numbers are indicated.
Eight-valve K7M 800
The Lada Largus model borrowed this engine from Renault Logan and Sandero. They are absolutely identical. For the first time, this unit began to be installed on the above-mentioned foreign cars in 2010, then it was a little more powerful, but due to certification according to the Euro-4 standard, its design was revised. The engine lost three horsepower, and its output was now 83.
A positive point in the eight-valve unit is that its resource, according to data from the manufacturer (Renault), is more than 400 thousand kilometers. The disadvantages of this motor can be noted based on the experience of using it not only on a Lada Largus car, but also on Logan:
- on Idling revolutions are not constant, floating;
- fuel consumption remains high;
- there are no valve lifters, as a result of which they need to be adjusted every 30 thousand kilometers;
- it is recommended to change the timing belt every 60 thousand kilometers, since when it breaks, the valve covers are bent;
- crankshaft oil seals often leak;
- high level of noise and vibration during operation.
Lada Largus is a rather heavy car, and the eight-valve unit does not always “pull”. This disadvantage has already been noted by not a single motorist. It is most difficult to use this engine when driving in yards. The lack of power is clearly noticeable when starting off.

For Russia, the great advantage of such engines is that they are very undemanding to fuel. Of course, you should not refuel in questionable places all the time, but the unit will not malfunction after using low-quality fuel several times.
Sixteen-valve K4M
This engine with a power of 105 hp. with. installed on seven-seater station wagons and used in a luxury configuration. It has significant differences from its brother with eight valves:
- fuel consumption in mixed mode - about 9 liters per 100 kilometers;
- quiet work;
- lack of vibration.
If you think which unit is better for Largus, then you should carefully consider the option with sixteen valves. It is more complicated, so the cost of a car equipped with such a motor will be slightly higher. Maintenance of a sixteen-valve engine will also take a lot of money from you, but at the same time you can easily drive over 450 thousand kilometers on it. It is only important to take care of it, listen to the advice of experts at the service station, change the components on time and not give too high a load.
Disadvantages of K4M:
- skip when using low quality fuel;
- insufficient dynamics;
- expensive spare parts;
- high prices for service in service centers.
If we compare two engines, then, undoubtedly, the K4M is more profitable, since it does not require frequent valve adjustments. Its shortcomings are not as significant as those of the eight-valve K7M.
Which unit is better to choose
If you want to buy a Largus, then you should buy a luxury package or a seven-door model, since in this case under the hood you will have a more reliable and modern engine model with sixteen valves. This is a more practical option, suitable both for driving in metropolitan areas with a lot of traffic jams, and for driving on the highway.
These K4M engines are produced in Russia (marking P) and in Spain (marked with the letter D in serial number). Despite the large number of jokes about the domestic auto industry, the build quality of the Russian unit is in no way inferior to the Spanish one. Changes in the operation of the production line have led to the fact that the motors released from the domestic conveyor are absolutely suitable for world standards. This was also noted by François Goujon, who is the head of the Power Units company.
Largus with a sixteen-valve engine has successfully overcome test drives. The only nuance was the use of the car in the summer, when the engine withstands the load from the switched on air conditioner. At low revs, the car goes with some effort, while when accelerating over 90 kilometers per hour, this disadvantage ceases to be felt.

What engine is on the Lada Largus: volume, models, resource
A roomy station wagon called Lada Largus is nothing more than a modified Dacia Logan MCV model. Renault in its station wagons offered different engines- from 1.4-liter to 1.6-liter 8 and 16-valve internal combustion engines. Two of them were initially available on Largus. We are talking about K7M and K4M engines, each with a volume of 1.6 liters. You can learn about which engine is being installed on the Lada Largus from the text. Let's say right away that the 8-valve K7M received a replacement, and the licensed production of the K4M internal combustion engine was established at AvtoVAZ.
Largus with 8-valve "11189" are already being produced. The proof is in the video.
Facts only (compression ratio, specifications)
16-valve gasoline engine Renault exists in several versions. The last of them, the most modern, meets the Euro-5 standards. It is interesting here that the compression ratio of the 16-valve Renault is 9.8. Remember this figure? And now - look: for an 8-valve VAZ engine, this figure is 10.5!
All VAZ ICEs, January 2016
It turns out that the VAZ engine needs more quality gasoline, since the compression ratio is higher.
Both engines in question are produced by the VAZ plant. And they both comply with Euro 5 standards. Their working volume is also the same, 1.6 liters. And the number of valves differs:
- K4M - 16 cl., 102 hp;
- 11189 - 8 cl., 87 hp
By the way, the 11189 engine looks better than its “predecessor”: it was Euro-4 - it became Euro-5, there were 84 “forces” - now it is 87! Only now the compression ratio of the K7M engine was 9.5. He was "omnivorous."
Service intervals for Lada Largus engines
All Largus motors are the same in terms of reliability: if the timing belt breaks, the valves will be bent. It is necessary to replace the timing belt on the K4M engine once every 120 thousand, on its "competitor" - every 75 thousand km. Not impressive. And here's how everything is with the oil change:
- K4M - 15,000 km + filter replacement;
- 11189 is the same.
By the way, according to Renault's regulations, it was necessary to change the timing belt every 60,000 km. But, as they say, it is written with a pen - do not cut it out with an ax. See what the VAZ “writes”.
120 thousand? Are they serious ??
If the timing belt breaks during the service interval, responsibility passes to the owner. Demand replacement according to Renault regulations, not VAZ.
16 valve engine - for those who are willing to pay more
It turns out that it is better to change the timing belt on a 16-valve valve more often than VAZ indicates in the regulations. On the other hand, the belt may well live up to 120 thousand. But still, if you don't want to risk it, reduce the service interval by half. Together with the belt, it would be better to replace two rollers, a tensioner and a guide.
Timing Belt Tension Adjustment
The Largus station wagon itself is not a budget model. And the complete set with "16-valve" will not be at all budgetary.
Torque of both engines (comparison)
Let's try to answer the question, which engine in the Lada Largus is the most powerful. Finding the answer will be easy if you analyze the torque graph.
K4M, 16 valves, 1.6 L
VAZ-11189, 8 valves, 1.6 l
Again the paradox turns out:
- At "idle" the force is equal to 100 N * m;
- Then both graphs grow linearly. However, the Renault engine turns out to be more high-torque, since at 2000 rpm it develops 135 N * m, and not 130, like the VAZ engine. Alas and ah.
Everyone is accustomed to the fact that at low revs the 8-valve should "pull" better. Perhaps everything will be so, if you do not compare the motors of two different companies. Draw conclusions.
For those who intend to buy a K4M engine - be sure to read it!
Be aware that any 16-valve engine is very sensitive to oil selection and quality. The engine in Largus at the plant is filled with imported material:
- SHELL PC 1448, 0W30
- ELF SOLARIS RNX, 5W30
At one time, LUKOIL Genesis RN oil was used, the viscosity of which corresponds to the 5W40 class. More about choosing an oil for 16 valve engine we already wrote here.
What "they have" goes as "5W30", we call "5W40".
Strict requirements are also imposed on the oil filter, if we talk about 16 valves. And with an 8-valve, everything looks simpler: the choice of oils has 20 options, and the filter can be changed "every other time" (but this is already against the regulations).
Two features of the Renault engine
The reader may have noticed that the K4M motors require more oil and it is necessary to fill it with low-temperature oil: 0W is for temperatures "lower than minus 35". The bottom line is that the engine really has problems with winter starting. But it also has a phase regulator to provide better traction at the bottom.
Phase regulator gear in two-shaft internal combustion engines Renault
On VAZ-11189 engines, there is no phase adjustment system.
For the Largus station wagons, the K4M engine was modified: the phase regulator was replaced with a conventional gear. Know this!
Hydraulic expansion joints fitted to the valve lifters make the K4M inaudible. In general, the combination "cast iron block + hydraulic lifters" is more typical for limousines. So consider that the Largus with 16 valves is a limousine. Requiring attention, quality service and expensive materials.

Official figures
AvtoVAZ does not exclude that its 89th engine will be “fed” with 92nd gasoline. This option is officially allowed. But for the K4M engine, only AI-95 gasoline is suitable, also A-95 or better.
- 8-cl .: 14.2 s, 158 km / h
- 16-cl .: 13.1 s, 165 km / h
The acceleration time from zero to 100 km / h is indicated here.
Be aware that different engines on Largus come with different boxes. In the first case (8 cl.) The gear ratio main pair equals 4.5. In the second - 4.2! We have already written about replacing the oil in them here.
In general, the Largus with an 8-valve is a family car that is not intended for high-speed travel. Acceleration "from scratch" on it goes very briskly, but this is due to the overestimated gear ratio. Thanks to him, from about 130 km / h, the dynamics disappears completely.
The VAZ company promises us the best efficiency just with the K4M engine, and not with the 11189. The numbers do not differ much, but they are in the region of 8 liters per hundred.

Largusology - Auto Review
I have been driving the Lada Largus station wagon with a Renault K4M engine for the third year already. And recently AvtoVAZ introduced engines of its own design to Largusy, with an index of 11189. How could you not compare this with mine? I also compared.
The VAZ-11189 motor has been known for a long time, Kalina and Granta are equipped with it. No technical fancy, two valves per cylinder - simplicity itself. As a result, it is more spacious under the hood; nevertheless, the introduction entailed a rearrangement of the engine compartment. The air filter, unified with Vesta, required a transfer expansion tank on the right side member, and the reservoir itself is applied from the XRAY model. A detail of bad fame: these burst constantly during our resource tests. It remains to be hoped that we have learned to weld the halves of the tank firmly.
Routinely, before testing, we first subject the machines to weight analysis. Moreover, we got the Largus with a VAZ engine (hereinafter - Vazolargus) in a seven-seat modification; there is reason to believe that it will be significantly heavier. Not guessing: it came out twelve kilograms lighter than my five-seater with a Renault engine (hereinafter referred to as Renolargus). The weight distribution is different for cars: the front end of Vazolargus is significantly less.
Of course, the masses were leveled for correct measurements; for this, in the process of work, assembled wheels were changed from car to car, so that each exercise was performed on the same tires. The fuel, AI-95, was also identical. Why? Although the "ninety-second" gasoline is allowed for the VAZ-11189 engine, however, the instructions indicate that all the characteristics were obtained on the AI-95, and it was poured into it.
Measurements of overclocking showed that the results differ by an insignificant one and a half seconds to "hundreds". And the maximum speed of Renolargus is as much as 10 km / h higher.

Largus engine: characteristics, malfunctions and tuning
LADA Largus is a roomy front-wheel drive station wagon of class "B", created on the basis of the popular model Renault Logan MCV. Initially, the car was equipped with French 1.6-liter engines - K4M (102 or 105 HP) and K7M 710/800 (86 HP). Since the beginning of 2016, Largus has been equipped with a VAZ 11189 engine, replacing it with an imported power unit similar in power and cylinder volume Renault unit K7M 710/800. The new Largus engine is a modified version of the VAZ 11186 engine, which was used to power LADA cars: Granta, Kalina and Priora. 
Operational and specifications station wagons largely depend on which engine is on the LADA Largus car. However, it should be noted that the use of a motor of its own production allowed AvtoVAZ to increase the level of vehicle localization up to 85%.

Description
The new LADA Largus VAZ 11189 engine completes the line of VAZ power units: 21083 - 21114 - 21116 - 11186.
Structurally, it is all the same in-line injection 4-cylinder engine with an overhead camshaft. The SONC timing belt is driven by a toothed belt.
Among the disadvantages of the Lada Largus engine, professionals note a decrease in the motor resource to 200,000 km, as well as the fact that when the timing belt breaks, the motor bends the valve.
In the process of modernization, the motor received:
- lightweight connecting rod and piston group;
- automatic timing belt tensioner;
- piston cooling nozzles;
- electronic throttle pipe of a new generation;
- metal cylinder head gasket;
- modern catalytic converter;
- new resonator-absorber of noise at the intake.
The changes made allowed:
- Increase vibroacoustic parameters.
- Increase power.
- Bring environmental characteristics to the level of the EURO-5 standard.
- Reduce fuel consumption.
Maintenance
The maintenance of the VAZ 11189 engine is no different from the standard maintenance of similar VAZ engines.
It includes:
- oil change every 15,000 km, but at least once a year. In this case, you need to fill in at least 3.2 liters of oil;
- checking and, if necessary, replacing spark plugs at each oil change;
- periodic inspection of the engine to detect leaks of the engine and transmission oil as well as coolant. If any defects are detected, they must be promptly eliminated;
- replacement of a drive belt after a run of 45 ... 60 thousand km.
Malfunctions
Tuning
All 8-valve engines manufactured by AvtoVAZ are tuned according to the same schemes. The VAZ 11189 Lada Largus engines are no exception.
The motor is tuned as follows:
- Atmospheric tuning without replacing the cylinder head
- replace the standard camshaft with a Nuzhdin 10.93 or OKB Dinamika 108 shaft;
- install the split gear;
- organize the exhaust using a 4-2-1 spider;
- install the receiver on top of the cylinder head;
- replace the staff throttle on the flap 54 mm;
- adjust the valve timing.
The qualified performance of these works will allow to increase the engine power up to 100 hp. with. By modifying the cylinder head (milling) and installing lightweight T-valves, you can bring the power up to 115 hp. with.
Similar results can be achieved by installing a PK-23-1 compressor (pressure 0.5 bar) and a Nuzhdin 10.42 or 10.63 camshaft on the engine.
- Turbine installation
The most in a simple way turbocharging of 8-valve VAZ 11189 engines is the use of whales based on the Garrett 17 turbine. By installing such a kit, you can increase the power of the power unit to 130 hp. with.
There are other ways to install a turbine, but they are large and expensive. In addition, 8-valve turbocharged engines are very sensitive to detonation, which ultimately leads to a significant decrease in engine life and the need for expensive repairs.
The optimal solution that will allow you to easily raise the power of the VAZ 11189 engine to 180 liters. with., is the replacement of the 8-valve cylinder head with a 16-valve one. After that, you can use any of the methods described earlier to tune the motor.

What is the engine on the Lada Largus?
Introduction
Lada Largus is the most prominent representative of domestic minivans, which, according to the Avtostat news agency, took the first position in terms of sales in its class from January to August 2016. The popularity of this model is growing not only in Russia and neighboring countries, but even in Germany.
A little about the models
Undoubtedly, each car has its own pros and cons, and Lada Largus also has those. Many are confused by the fact that the car is domestic, but representatives of the board of directors of the automaker, as well as European experts claim that the quality of the car and its assembly meet European standards.
Each engine has its own pros and cons
The Largus model itself was released in 2012. After entering the market, its popularity began to grow. The minivan was created on the Nissan-Renault platform and combined aesthetics, grace and practicality. Good capacity and good cross-country ability were only in the hands of manufacturers to increase those who want to buy this car. The car model was presented in two variations: passenger and cargo. If the characteristics of the cargo version, by definition, are aimed at carrying capacity, suspension strength, "endurance" when transporting heavy loads. In the passenger modification, the emphasis is on comfort, interior decoration, smoothness and speed.
In developing the engines, a lot of factors were taken into account, among which the main ones were far from ideal climatic conditions for any car, including severe winter frosts with high humidity, sharp temperature changes. Also an important aspect is the road conditions themselves. It is far from everywhere possible to move harmlessly on the roads, especially in regions remote from the capital.
The dimensional characteristics of the car are as follows: the body length is 4.45 meters, the width is 1.74 meters, and the height is 1.63 meters. The trunk in each model is very spacious, its volume is about 560 liters. Passenger cars also have good capacity. They can easily accommodate from five to seven people.
Types of Lada Largus engines
It is necessary to consider in more detail the options for motor lineup Lada Largus, so that everyone can determine the most suitable one for themselves.
1 - air conditioner compressor; 2 - drive belt; 3 - generator; 4 - power steering pump; 5 - oil dipstick; 6 - cylinder head cover; 7 - ignition coil; 8 - tips of BB wires; 9 - cylinder head; 10 - thermostat housing; 11 - exhaust manifold; 12 - water pump pipe; 13 - sensor of insufficient oil pressure; 14 - plug; 15 - flywheel; 16 - cylinder block; 17 - oil pan; 18 - oil filter
Today, depending on the configuration, Renault engines with a capacity of 90 and 105 horsepower are installed. It is two gasoline engine, in-line execution, equipped with four cylinders with a volume of 1.6 liters. The engine in all cars is located at the front, across the body.
Eight valve engine
The volume of the power unit is 1.6 liters, the power that it is capable of developing is 84 horsepower. This unit is often installed on a model of the "norm" or "standard" class.
Sixteen valve engine
This engine is slightly more powerful than the eight-valve. Its power is about 105 horsepower. Such units are installed on the luxury configuration.
Both Renault-Nissan engines work in conjunction with a five-speed manual transmission. The machine is not yet planned to be installed on the Largus model.
"Largus" engines are characterized by high elasticity, and mechanical box gear responds clearly to all switching on and off. In order to perform a confident overtaking or briskly get under way from the start, the power of the engines is quite enough. Both the eight-valve and sixteen-valve engines comply with Euro 4 emission standards.
On all cars, depending on the configuration, it is possible to install additional equipment:
- manual steering model without amplifiers;
- a car with manual steering with climate control adjustment;
- a car with power steering;
- car model with hydraulic booster and climate control adjustment.
- Some calculations from the technical characteristics of the K4M and K7M Largus engines:
- fuel: gasoline AI-95 and higher;
- fuel injection: distributed, electronically controlled;
- engine cylinders: both motors have 4 cylinders arranged in a row;
- number of valves: K4M - 16 cylinders, K7M - 8 cylinders;
- nominal displacement of the power unit: 1598 cm3;
- maximum torque (at what speed is achieved): K4M - 148 at 3750, K7M - 124 at 3000;
- working volume of oil with an oil filter: K4M - 4.8 liters, K7M - 3.3 liters.
K7M characteristics
These power units were successfully installed on the Renault Logan, Renault Sandero, and now on the Lada Largus. Until 2010, the K7M 7100 engine was successfully produced and worked. After modernization, it was replaced by the K7M 800, which structurally did not have any differences, and the difference between them was in the number of horsepower, their number decreased (there were 86 "horses", now - 83 ). And also changes were made in terms of environmental indicators. The new engine belongs to the Euro-4 category.
However, the disadvantages have not gone anywhere:
- Fuel consumption remains high and remains;
- There is a problem with floating idle speed;
- It is necessary to adjust the engine valves almost every 20-30 thousand kilometers;
- There are no hydraulic compensators;
- It is recommended to change the timing belt every 60 thousand kilometers;
- After prolonged use, more than 70-90 thousand kilometers, crankshaft oil seal leaks may occur;
- The engine makes too much noise during operation;
- Vibration in the engine may occur during long-term operation at higher speeds.
If we consider the advantages of the engine, then among them the reliability of such power units stands out as a bright spot. According to the plant, the engine resource is declared about four hundred thousand kilometers, although in real conditions it may be slightly more.
K4M characteristics
This motor was also successfully installed and works to this day on Renault Logan and Renault Sandero cars. Also, they began to install it on richer "> configurations Lada Largus. Among the bright advantages, unlike the K7M, this unit is much quieter, more economical, and also does not have vibration during long-term operation.
However, there are still disadvantages:
- Spare parts for such elements are very expensive;
- The timing belt will have to be changed every 60 thousand kilometers, otherwise, if it breaks, all the valves will be bent;
- Failures can occur;
- If low-quality fuel gets into the car, then it will immediately react to it with floating idle speed;
- If the unit is no longer new, but rather worn, it can be a little triple.
Still, if you make a choice between two foreign options, then it is best, of course, to make a choice in the direction of a more modern and powerful motor - K4M.
Whose engine is Largus really
Initially, as already mentioned, the engines for Lada Largus were produced at the Renault plant in Spain and supplied to Russia in full assembly. However, now, since December 2015, K4M engines (sixteen-valve, one hundred and five strong) have been produced at the AvtoVAZ concern. Referring to the words of the Director of the Power Units project, the engines all have high production efficiency, are thoroughly tested and meet the most stringent requirements of European standards. François Goujon is confident in the success of this project and is ready to make considerable efforts to further develop new models of units for Russian cars.
According to AvtoVAZ representatives, all engines comply with international standards, the personnel are constantly trained and receive additional professional skills in working with new elements. Production control technology has one important aspect: a randomly created engine is selected weekly and tested on several stands, and then disassembled for internal study.
As has been mentioned more than once, since the end of 2015, the AvtoVAZ concern has begun installing its own designs on some Largus models - VAZ 11189 8-valve engines. Until that time, these engines have successfully shown themselves in work on models such as Lada Granda and Lada Kalina. This engine model is perfectly adapted to the VO platform with a separate subframe.
Unlike the French, the domestic engine has a greater number of "horses", 87. The torque is about 140 instead of 124 Nm. With the new Russian engine, cars have become several times more economical, the average consumption has become about 8.2 liters per hundred. And one of the most important and main indicators - the cost of the "naked" VAZ11189 is thirteen thousand cheaper than the French unit.
Let's sum up
Lada Largus - modern car, which can be presented in various variations and assemblies. In fact, you can put any engine on it, and it will work faithfully for a long time, however, fans of faster and quieter driving will confidently choose the European K4M. All installed engines have some differences, but no global changes will occur and Lada Largus will be on the leaderboards of the rating for sold cars in its class for a long time.

Lada Largus 2012 after 105 thousand km - Behind the wheel magazine
May 6, 2017Time flew by. It seems that only yesterday Largus ran in and started in a high-speed 60-hour marathon, and today the number on the odometer has become six-digit. The character of the car is already visible in the first thousand, some nuances of operation appear a little later, and something specific about reliability can be said only when the mileage is at least hundreds of thousands of kilometers. So it's time to talk about the reliability of Largus.

Over the past 40,000 km since the last report, our Lada with Franco-Romanian ancestry has several times arranged unpleasant surprises. However, these malfunctions did not require urgent elimination, for which special thanks to Largus.
The most curious riddle was thrown by a failed thermostat. When driving on the highway, the engine began to cool down - this was noticeable both by the temperature sensor and by the cool air from the heater deflectors. The thermostat was changed. The original was not found in the nearest store, so we purchased an analogue from Era. The engine cooling system worked properly again, but not for long - after a few hundred kilometers, the symptoms recurred. I already, really, began to doubt that the reason was in the thermostat, but all the signs stubbornly pointed to its malfunction. In search of a good thermostat, I searched the Internet forums, interviewed servicemen and sellers - and opted for a product from the renowned company Gates. I hope I was not mistaken. For at least 30,000 km, the thermostat has been working flawlessly.

Test drive Lada Largus
Large budget wagon Renault / Dacia Logan MCV, created on the basis of the Logan sedan, appeared in Europe back in 2006. But such a car reached Russia only in 2012 under the name…. Lada Largus!
As for the exterior, Lada Largus looks almost the same as the Romanian-French "donor". Appearance the car is thoughtful, simple and quite attractive, without any frills. But this is not the main thing in a family station wagon, so in this case you want to quickly get behind the wheel, evaluate the ergonomics and test it on the go.
The interior of the Lada Largus migrated from the Logan almost unchanged. Dashboard ergonomic and functional, the center console is simple, well thought out and contains the main controls. At the same time, there are a lot of ergonomic miscalculations: the front power window buttons are located on the center console, the rear ones are between the front seats, the windshield washer is activated separately from the wipers, the seat heating start button is very difficult to find, and the sound signal is based on the end of the left steering column switch.
The car is available in a five- or seven-seater version. Sitting in the front is comfortable, lateral support is moderately developed, the rear seat passengers have enough space, and it is quite tolerable in the gallery, even if you can't hold out there for a long time.
But most importantly, how the car behaves on the move. For Lada Largus, two petrol engines with a volume of 1.6 liters each are available - an 8-valve unit producing 87 horsepower and 128 Nm of peak torque, and a 16-valve engine with a return of 105 “horses” and 148 Nm. They are combined exclusively with 5-speed "mechanics" and front-wheel drive.
Well, having driven the 87-horsepower version, everyone will understand - for a large station wagon, the engine is clearly weak. If at the bottom the engine has a decent supply of traction, then at high revs its potential is noticeably reduced. An empty car drives well, however, its acceleration is sluggish both from a standstill and from medium revs, and if you completely fill the cabin with passengers, and even load a few bags, then the lack of power begins to be felt at every step. When driving around the city, this is not so pronounced, but on the highway it is very noticeable, especially when overtaking. In this case, it is better to calculate the trajectory in advance, and in climbs - and not to risk it at all. The optimal speed for such a "Largus" is 100-110 km / h, further acceleration proceeds slowly, and the engine begins to roar noticeably, delivering acoustic discomfort. The 105-horsepower engine also does not present surprises. The five-seat version takes 13.1 seconds to accelerate from 0 to 100 km / h, and the seven-seat version takes 13.5 seconds. Of course, if you drive with an empty interior and trunk, then its capabilities are quite enough even for those who like rather active driving. And if you increase the load, it becomes clear that the motor is frankly sluggish, and some noticeable acceleration begins only after the engine is cranked up at 3,500 rpm. But it should be noted that even in a fully loaded state, this power unit allows you to keep up with the total flow. But in the nature of the motor there is a more important trait for a large station wagon - it is elasticity, thanks to which you can drive at low revs, without constant switching. The first gear of the Largus station wagon is too short, just like that of Renault Duster... Most likely, such a move was taken to compensate for the small traction reserve at low revs. And if you drive at a speed of at least 50 km / h, then you don't have to switch to a lower gear at all - the engine confidently accelerates a difficult car in fifth up to maximum speed. By the way, the car can gain the passport "maximum speed" even at full load, though it is not easy for him. In addition, in this case, there is a lack of sixth gear - at a speed of 110-120 km / h, the unit is too loud. As for the "appetite", Lada Largus with a 105-horsepower engine is rather moderate - an average of about 9 liters of fuel per 100 km of run.
Disc brakes are installed on the front of the Lada Largus station wagon, and drum brakes on the back. The car has no noticeable problems with braking, but the efficiency of deceleration and the information content of the middle pedal clearly do not reach those of foreign cars. The Largus is managed surprisingly well. Banks are observed in all directions, however, in general, he behaves in a collected and intelligible manner. At normal speeds, the car is understandable and predictable.
But the Lada Largus suspension deserves only praise! Still, after all, he got it from "Logan", retaining all its energy intensity. The car is ideally adapted to Russian roads. Potholes, pits, potholes, bumps, cracks - the machine literally ignores them. But still, cargo "notes" make themselves felt - on small irregularities, the suspension is stiff.
Station wagon Lada Largus is a car with its own advantages and disadvantages. The main advantage of the car is its spaciousness and practicality. Good transformation possibilities make Largus truly versatile: the third row of seats can be removed, and the second one can be folded (or also removed), thereby obtaining a useful volume of more than 2 cubic meters. An unkillable and energy-intensive suspension is another big plus in the car's piggy bank, as well as affordable price, excellent maintainability and availability of spare parts.
But not everything is as good as it seems at first glance. Noise isolation is one of the main disadvantages of Lada Largus. Its lack is especially evident at high speeds. There are also serious problems with the ergonomics of the cabin, in particular with the location of some of the controls. The car could use more powerful engines and a 6-speed gearbox. The dynamics are not encouraging, and the thrust reserve at full load is not always enough.
One conclusion can be made: for its money, Lada Largus is a good family car, in which in the first of the "Lada" you feel almost like in a "foreign car".
Lada Largus engines are 8 and 16-valve gasoline units. It is no secret that the domestic Lada Largus is nothing more than the first generation Renault Logan. Accordingly, the engines there are from Renault, but not everything is so simple. Indeed, since December 2015, the manufacturer decided to replace the 8 valve engine with 84 hp. ( Renault K7M), on the domestic eight-valve VAZ-11189 with a capacity of 87 h.p. In addition 16 valve motor Renault K4M(105 hp), which was previously transported from Europe, is now produced at Avtovaz and produces only 102 hp. But the drop in the power of the 16-valve engine is not due to some kind of design changes, but to reconfiguring the injection system to comply with the more stringent Euro-5 environmental standard. Today we will tell you about all Lada Largus motors.
Engine device Lada Largus 1.6 8 valves
Petrol Renault engine The K7M on the Largus produced 84 hp. Structurally, it is a four-stroke, four-cylinder, in-line, eight-valve, with an overhead camshaft. The order of operation of the cylinders: 1-3-4-2, counting from the flywheel. The engine power supply system is MPI distributed fuel injection. The engine with the gearbox and clutch form the power unit - a single unit fixed in the engine compartment on three elastic rubber-metal bearings. The right support is attached to the bracket on the top cover of the timing belt, and the left and rear support to the gearbox housing. The engine block is cast from cast iron, the cylinders are bored directly into the block. The nominal cylinder diameter is 79.5 mm. The motor was assembled at the Romanian Dacia plant.
The cylinder head of the engine Lada Largus 1.6 8 valves
The cylinder head of the Lada Largus 1.6 is cast from an aluminum alloy, common to all four cylinders. It is centered on the block with two bushings and secured with ten screws. A non-shrinkable metal gasket is installed between the block and the head. There are five camshaft bearings (bearings) at the top of the cylinder head. The supports are made one-piece, and the camshaft is inserted into them from the timing drive side. The camshaft is driven by a toothed belt from the crankshaft.
Timing drive engine Lada Largus 1.6 8 valves
The timing drive on the Lada Largus 1.6 8 valves is carried out according to the following scheme (image just above) - the torque from the crankshaft pulley is transmitted to the camshaft pulley by rotating the coolant pump pulley. The belt is tensioned with a special roller that changes with timing belt... If the belt breaks, the valve bends. The belt must be replaced every 60 thousand kilometers.

We will not talk in detail about the Russian engine VAZ-11189, which today replaced the old 8-valve under the hood of Largus. Since the motor is quite common and is found on many Lada models. Structurally, the unit originates from the first front-wheel drive VAZ-2108. 4-cylinder aspirated, with a cast iron cylinder block and a timing belt. Unit power 87 HP (64 kW) at 5100 rpm. The torque is 140 Nm at 3800 rpm. The engine is designed for AI-92 gasoline.
Engine device Lada Largus 1.6 16 valves
Largus engine Renault K4M power of 105 horses, which after "flashing the brains" began to comply with Euro-5 and produce 102 hp. Initially, the motor was brought from Spain (from the Renault plant), but now it is produced in Togliatti with a high degree of localization. This is a 4-cylinder 16-valve unit with multipoint fuel injection and a timing belt. At the heart of a cast iron block. The cylinders are bored directly into the block. The order of operation of the cylinders: 1-3-4-2, counting from the flywheel.
The cylinder head of the Lada Largus K4M engine
The head of the Lada Largus 1.6 liter engine block (16 valves) is aluminum with two camshafts and hydraulic lifters. That is, the thermal clearance of the valves does not need to be adjusted manually. And all thanks to the hydraulic support of the valve levers, which are installed in the sockets of the cylinder head. A hydraulic compensator with a ball check valve is installed inside the hydraulic support housing. Oil inside the hydraulic support comes from a line in the cylinder head through a hole in the hydraulic support housing. The hydraulic mount automatically provides backlash-free contact between the camshaft cam and the valve lever roller, compensating for wear on the cam, lever, valve stem end, seat chamfers and valve disc.
Timing drive engine Lada Largus 1.6 16 valves
The camshaft drive Lada Largus 1.6 is carried out by a toothed belt from the crankshaft pulley. On the shaft next to the first (counting from toothed pulley camshaft), a thrust flange is made with a support neck, which, when assembled, enters the grooves of the block head and cover, thereby preventing axial movement of the shaft. The camshaft pulley is not fixed on the shaft with a key or pin, but only due to the frictional forces arising on the end surfaces of the pulley and shaft when tightening the pulley nut. A belt break or jumping a few teeth usually leads to disastrous consequences, because this engine is definitely valve bends... The timing belt is replaced every 60 thousand kilometers or after 4 years, whichever comes first, regardless of its condition.
Technical characteristics of the engine Lada Largus 1.6 16 cl.
The Largus station wagon turned out to be an incredibly popular and reliable model. The secret of success turned out to be in the fantastic practicality of the roomy car.
The Largus car presented today by the concern is a joint project of the domestic auto industry and the French Renault corporation. This car model has been produced since 2008. In many respects, "Largus" copies the Renault Logan MCV model (production began in 2006), having only distinctive radiator grilles, parts of the cladding and, in fact, the manufacturer's logo.
External characteristics
In many ways it predetermines which engine will be installed on the Largus, but regardless of this, the external dimensions of the vehicle will remain standard.
Judging by them, we can safely attribute the car to the largest among the B-class:
- clearance - 16 cm;
- base - 2 meters and 90.5 cm;
- length - 4 meters and 47.3 cm;
- width - 1 meter and 74 cm;
- height without rails - 1 meter and 64 cm (with rails 3.4 cm higher).
With standard dimensions, you can purchase a car in the modifications of a cargo van or a passenger car. The latter, in turn, can also be 5-seater or 7-seater. Depending on the selected modification, the volume of the luggage compartment will differ. So, freight vehicles have only 2 seats for passengers and a load compartment volume of 2540 liters. The modification for 7 passengers will only accommodate 198 liters of luggage, and the 5-seater - already 700 liters. If you additionally fold the rear row seats, you can increase this volume to 2350 liters, and this is almost like the cargo version.
In general, the exterior of the car is restrained, and its main advantage is spaciousness. Perhaps that is why its name is translated from Latin as “generous”. For ease of use of large volume luggage compartments they are equipped with swing doors. The total glazing area of the car is large, all lines are straight, simple rectangular shapes.
Salon features
Depending on the configuration, not only Largus engines can be changed. The fully equipped offer for the car has the ability to adjust the lumbar support, power steering, front power windows, air conditioning, ABS and a radio tape recorder. V standard configuration the salon has a lift for the chair, vertical steering wheel adjustment and a well-read front panel, which is a noticeable difference compared to the Logan MCV.
There is a lot of space in the cabin, but rear seats passengers of any height and weight can comfortably accommodate. If necessary, the seats can be removed or folded altogether. The car interior is also equipped with side and front airbags, three-point belts and a retention system Passive safety passengers are provided with a special body structure that allows you to redistribute the impact thanks to the front subframe.
Main working parts
In general, Largus engines have minor differences in reliability and the type of fuel used (only gasoline). Their volume is always 1.6 liters and functions only in conjunction with a mechanical five-speed gearbox gear. Due to the Euro-4 requirements, the Largus engines had to be revised at one time, and they lost a little power. Now the 8-valve powertrain only has 83bhp. with., and 16-valve - 103 liters. with. The difference in their work is noticeable in the acceleration time to 100 km / h, maximum speed and other dynamic indicators. So, an engine with a capacity of 83 liters. with. capable of accelerating to 100 km / h in 14.5 seconds and keeping the maximum speed at around 156 km / h. Another modification of the power unit is already capable of demonstrating a similar acceleration in just 13.1 seconds, and its maximum speed is at around 165 km / h.
The chassis, front suspension and went to "Largus" from its predecessor Renault-Dacia Logan MCV. Of course, they have been strengthened for stable operation in our climate and bad road conditions. When buying a car, you should pay attention to the turning angle of 11.5 meters.
General characteristics of engines "Largus"
Despite the fact that the power units for this car were completely developed by the French concern, the engines are fully adapted to the conditions of the Russian climate. Each of them, regardless of modification, can be used in severe winter conditions, off-road conditions and even sharp temperature fluctuations, which is typical of some regions.
Regardless of the valve system of the Largus engine, the first oil change should be filled only with what is indicated as standard. At different times, the company changed oil manufacturers, so special attention should be paid to this issue.
It is interesting that engine manufacturers set a service life of only 160 thousand kilometers on them, while completely different indicators are indicated in the passports for power units when purchasing.
Eight valve engine
This modification of the power unit was at one time borrowed from the "Logan" and "Sandero" car models. For the first time, these engines were installed on cars. foreign production 7 years ago, but after the need to comply with Euro-4 environmental standards, their designs had to be revised, which led to a slight loss of power.
According to the manufacturers, the resource of this unit is 400 thousand kilometers. The 8-valve engine "Lada Largus" receives positive reviews from consumers not only for a good resource. An important condition for many is the unpretentiousness of the unit to fuel. Of course, regular use of low-quality gasoline will affect the operation of the car, but several low-octane fuel fillings will not harm.
Disadvantages of the unit
According to the opinions of motorists, the main disadvantages of work can be identified this engine:
- high fuel consumption;
- high noise level;
- noticeable vibrations during work;
- floating idle speed;
- the need to adjust the valve every 30 thousand runs;
- the need to replace the timing belt every 60 thousand runs;
- the frequency of crankshaft oil seal leaks.
Also, drivers note that the power of this engine is not always enough, especially at the beginning of the movement and in the yards.
16-valve modification
The engine on the Largus K4M is installed only on a 7-seater station wagon and in luxury car trim levels. Its main distinguishing features are: quiet operation, no vibrations and fuel consumption in mixed mode of only 9 liters per 100 km.
Disadvantages of the unit
16-valve Largus engines also do not always have only good reviews. Among the disadvantages of the power unit, many note the lack of dynamics and misfire when using low-octane fuel. Of course, the complexity of the assembly of this unit also affects its cost.
The price for its maintenance will also be noticeably higher (in comparison with the 8-valve one), but at the same time the manufacturer gives a guarantee of operation of 450 thousand kilometers, and with proper care and timely inspection, the engine will last longer.
In general, when choosing between two engine models, the more powerful is also more profitable, since it does not require frequent valve adjustments.
Which engine is the best?
The undoubted conclusion from many opinions is that when choosing an engine for the Largus, one should pay attention to its most powerful model. Only a 16-valve unit can boast of maximum reliability and practicality, since it demonstrates itself equally well in the conditions of both the highway and the city.
Models of "Largus" with and of Spanish production are produced today. You can determine the place of their assembly by the markings on the power unit: assembled in Russia - P, assembled in Spain - D. Interestingly, these engines do not differ at all in quality. Perhaps this was the replacement of the production line, which now meets all international standards. In general, the standard jokes about domestic auto industry in this case will be inappropriate.
The nuance of using a car with a powerful engine installed was only its operation in the summer, when the air conditioner was turned on in the cabin. Low rpm At the same time, the power unit is felt with some effort, but at speeds above 90 km / h it ceases to be felt.
Fundamental differences between engines
The tradition of producing the same car model with the ability to purchase it with different engines internal combustion AvtoVAZ started with the production of the tenth Lada model. Interestingly, the "head" of the power unit there could even be replaced independently. Today, various modifications of cars are offered to consumers in the person of "Largus".
Thanks to simple mathematics, it can be determined that in the simplest engine model there are 4 cylinders, each of which has 2 valves. This feature negatively affects gas exchange and the intake and exhaust system, which means that it reduces the efficiency of the car and increases fuel consumption.
In fact, thanks to the painstaking work of engineers, narrow the gap between fuel consumption in different modifications engines turned out to be almost zero. Thus, technical characteristics are not significant factors of choice, but the cost of power units with a different number of valves still differs noticeably.
More new model Largus Cross has only a 16-valve engine. This is due to the approach of the car to the luxury class. In addition to the powerful engine, its standard configuration has other advantages that are available in conventional models only with a surcharge or a high-comfort package.
In any case, it should be remembered that absolutely all models of Largus cars are assembled on modern conveyor lines and meet all international standards. Does it make sense to pay more for the number of valves with practically the same characteristics - this, of course, is a personal matter for every motorist.
For a long period, AvtoVAZ had a difficult goal - to create a car balanced in terms of consumer qualities. The aspiration came down to the idea of releasing a "workhorse" that would be equally well suited not only for family use, but also showed sufficient efficiency in the field of logistics business.
At the first stage of the concept implementation, the interaction of Togliatti residents with the European giant Renault was traced. Thanks to this cooperation, a universal model Lada Largus was born, which was built on the basis of Logan. Many are interested in what engines are put on these versions? The platform was chosen correctly, and it turned out to be so successful that it still serves to build various models, such as: Duster, Sandero, as well as the Nissan subcompact family.
To transform Logan into Lada Largus, the developers did not need to do so many improvements. Much attention was paid only to the chassis and appearance. Let's talk about what engines are installed on the car.
Lada Largus motors
What motor is worth? Here, the manufacturer also did not rush to extremes and, without a shadow of hesitation, used power units from Logan.
These are two versions of engines with a similar volume equal to 1.6 liters:
- 8-valve version "K7M", capable of reproducing 86 hp. with.;
- its modification "K4M" has a 16 valve engine, the output of which is 105 "horses".
AvtoVAZ made its contribution by offering the 11189 power plant installed on Vesta. Let's honestly say that this motor was installed on Grant, but only here it was "brought" to comply with the Euro-5 standard.
We are most interested in a “couple” of rival motors: a 16-valve engine versus a domestic 8-valve unit “11189”.
How do the owners respond to the motors of their Lada Largus station wagons? Today's Internet is overloaded with a variety of information regarding both options for equipping the Lada Largus. We tried to find the most worthy reviews for the intriguing rivalry we are considering. And also figure out who has which motor?
Car owners reviews
Alexey Radishchev, Nizhny Novgorod, compares Kalina with Largus in a 16-valve version.
I was really lucky. I was the owner of both domestic models: I operated Kalina with an 8-valve engine, and I got Lada Largus with a new 16-valve unit. After making a comparison, I decided to write a review according to my feelings.
By the nature of my activity, I am engaged in construction, so my Kalina is often loaded to capacity. Sometimes it was necessary to load half a ton. In general, with the engine "11189" the car is quite high-spirited, which motor is worth, I think, everyone knows, even in long climbs it manages to overtake. The 8-valve engine is good. It can be seen that the engineers have tried.
In terms of carrying capacity, Largus, of course, wins, but the weight of this car is also greater. The car cannot be called frisky. I even did chip tuning, but my station wagon refuses to show agility even in an unloaded state. Therefore, I made, as it seems to me, a reasonable conclusion: the borrowed K4M engine, although it has a 16-valve “head” design, is not able to drive briskly. Now I'm thinking of changing Largus to another option. For example, on the same Kalina, but only to be newer.
Innokenty Vinnik, Lipetsk, Kalina 2, VAZ 11189 engine.
I have been riding Kalina 2 for the last couple of years. I live in a village, in connection with which I have to transport a lot of goods of different nature... In general, my car is constantly loaded to capacity. I hardly face any problems in operation. I adjusted the valves a couple of times. I don't take standard service here. During these 2 years my Kalina "ran" almost 20 thousand. I don’t worry about the engine at all, since the 8-valve unit “11189” in the event of a malfunction will not be so expensive to repair. I pour oil only for semi-synthetics.
A neighbor drives a LADA Largus and, in general, does not speak very flatteringly about his car. One day he offered me a ride; the car was not loaded. I was surprised to hit the gas. The dynamics are not felt at all. Maybe the Euro-5 standard is to blame here, which forced the engine to be modified. If the engine on my Kalina breaks down, then repairs will not hit my pocket. But what about the 16-valve unit? There, repairs will cost a decent amount.
Constructive simplicity is, in my opinion, the main advantage power plant"VAZ 11189" in comparison with the French engine.
Stepan Uspensky, Largus with a 1.6 liter unit. (105 "forces") 2014, Saratov.
In general, the car is not bad and will delight you with its capacity. She has one small and unpleasant feature. It's about fuel consumption. Reaching the declared 6 liters in the suburban mode is possible only at a speed of no more than 60 km per hour. Few people will like this situation, because "trudging" at this speed on the track is not the most pleasant thing.
The manufacturer claims that the 16-valve variation of the motor is economical, but in reality this is far from the truth. It's hard to tell right away how much chip tuning is needed for a car to receive positive reviews? There is no decent dynamics. At a speed of about 90 km per hour, the car "eats" all 9 liters for the traversed "hundred". Will not work!
The compressor of the interior air conditioning system is driven by the engine through a clutch, which also affects the loss of power, and accordingly increases the level of consumption.
Alexey Vladimirsky, 5-seater Lada Largus, 8-valve unit, Anapa.
It's nice when domestic car new! It is, as expected, better than a well-worn foreign car. Taking into account what engines are installed. After transplanting to LADA Largus I felt a lack of practical little things. Although you get used to it over time. This vehicle can be regarded as a good compromise when it comes to balancing cost with quality.
In the "11189" engine, everything suits me, although the consumption is too large. The results I have obtained in practice strongly differ from the data presented by the manufacturer. If you accelerate to 130 km per hour, then the consumption will be at least 10 liters. And this is on an unloaded car. I'm afraid to imagine how gasoline will "go away" if the car is fully loaded.
I will say that the 8-valve unit is frankly weak for such a body as in LADA Largus. A more efficient motor would be appropriate here.
Now about the fifth gear. Some owners write that the engine starts to "roar" on it. I noticed that at a speed of 3000 rpm, the speed is 100 km per hour, and at 4 thousand, respectively, it reaches 120 km per hour.
