126 motor description of design features

The Lada Priora engine is installed on the VAZ 2170 and its modifications. In the cylinder-piston block of the 21126 engine, the cylinder walls are well processed by honing to obtain improved internal surfaces. The 11183 cast iron crankshaft features a larger crank radius. The original gear pulley is indexed with a special number 21126.

The semicircular profile of the teeth ensures engagement with the proprietary belt, which has 137 teeth of the same profile, of the gas distribution mechanism. The service life of a Gates toothed belt is 200 thousand km.

The connecting rod and piston group was developed by Federal Mogul. Engineers have created a design that weighs 30% less than the 2110 model. Piston rings Federal Mogul are thinner. In order to reduce friction losses, the connecting rod is thinned and its head does not touch crankshaft. To install the connecting rod cover, original disposable bolts are used. Width of new connecting rod bearings equal to 17.2 mm.

Thinner piston rings, upper compression and lower compression, have a height of 1.2 and 1.5 mm, respectively. Oil scraper ring made with a height of 2 mm.

The cast iron cylinder head 21126 - 1003011, designed for Priora with 16 valves, has a platform suitable for the new timing belt tensioning mechanism. The head is cast together with the glasses of the wells for candles.

The cylinder head gasket has two metal layers, its total thickness is 0.45 mm. The design of the part provides special holes for cylinders. The diameter of each hole is 82mm.

The catalytic converter - catcollector model 11194 - 1203008 - 10(11), ensures compliance with the requirements for Euro 3 toxicity standards. For Euro 4 standards - model 11194 - 1203008 - 00(01), respectively.

Changes have been made to the water pump to extend its service life - the use of bearings and seals of a different type.

Ignition system and fuel system The power unit does not differ from the VAZ 11194. Spark plugs for Priora 16 valves are equipped with individual ignition coils. Fuel rails made of stainless steel are suitable for installing branded SIEMENS or BOSCH injectors that supply fuel in accordance with certain phases.

The universal scheme of the lubrication system consists of the following components:

An oil pump consisting of gears.
Steel crankcase under the cylinder block.
Oil filter.
Oil pressure sensor.

The electronic control system of the engine is equipped with a January 7.2 or M 7.9.7 controller.

Factors affecting the service life of the VAZ 2170

According to the manufacturer, the ICE 21126 with sixteen valves has a stable operation duration of 200 thousand kilometers. After a certain mileage it is necessary to carry out major repairs. Careful attitude for VAZ 2170, in working order Maintenance(Maintenance) and timely replacement of damaged components and parts will lead to a long service life of the vehicle.

Reasons affecting the service life of the power unit:

Engine overheating. Elevated temperatures of a running engine negatively affect the overall service life of the motor. Maintaining the operating temperature of the power unit elements at a constant level significantly extends its operating time.
Fuel. The vehicle owner's manual contains detailed information about the recommended brand of gasoline. Filling the 16-valve Priora engine with fuel must be of proven quality.
Machine oils. What oil is better to fill, its brand and how much is needed lubricant indicated in the accompanying documentation for the car. The 126 sixteen valve engine accepts semi-synthetic and synthetic motor oils most well. Complete replacement Oil inspection should be carried out annually or after a mileage of 15 thousand kilometers.

The optimal operating engine temperature is 90 - 95 °C. The rules allow the power unit to operate at temperatures reaching up to one hundred degrees, provided that the radiator fan is running. The engine temperature is considered low if it is below +90°C. In cold weather, it takes more time to warm up the engine to the desired mark on the device.

When servicing your VAZ 2107 car, the car owner can change the oil with his own hands. To do this, you need to know how to drain used lubricating fluid, what kind of oil to pour into Priora and how much motor oil pour into the neck.

Are the valves bending?

In Lada Priora cars, even in a 16-valve 126 power unit, valves can often bend. The reasons causing this defect lie in non-compliance with operating rules, in case of violation of the regulations for replacing the following components and parts:

rollers;
timing belt;
water pump.

If one of the listed components breaks down, the pistons, exerting mechanical stress on the valves, can bend them. The design features of the engine are the reasons why the engine can bend valves. Deformation of the valves necessitates a major overhaul of the Priora engine.

To avoid this defect, the car owner needs to timely check the timing elements. Of particular importance is the belt, which is subject to thorough inspection after 50 thousand kilometers. When checking, the following faults are excluded:

cracks;
delamination;
ruptures.

The rollers and timing pump 126 must also be inspected, because The motor bends the valves even when they malfunction.

Signs of wear on the belt and other timing components are vibrations and an unpleasant grinding noise in the engine compartment. In this case, it is necessary to urgently repair or replace the broken elements to avoid deformation of the engine valves.

Why does the engine stall?

Among the most common breakdowns of this power unit, defects such as unstable work and engine tripping. Such failures occur due to malfunctions in engine components and parts:

decrease in fuel pressure;
defects in gas distribution mechanism elements;
sensor malfunctions;
violation of tightness in hoses;
faulty throttle valve.

The power of the power unit is reduced for the following reasons:

low compression in one or more cylinders;
burnout of gaskets;
wear of cylinder walls;
erasing piston rings;
deformation of pistons under the influence of high temperatures.

Engine friction can be eliminated by flushing the injectors. Causes unstable work power unit may be due to a malfunction of the following devices:

spark plugs for Priora 16 valves;
ignition coil;
throttle valve;
regulator idle move;
battery;
starter;
ignition coil;
gasoline pump;
fuel filter;
fuel pressure regulating device.

You can replace the spark plugs on Priora yourself. To do this, you need to familiarize yourself with the principles the right choice and replacement of these nodes described in special articles on the Internet.

Priora engine tuning

To improve the power performance of the Priora power unit, they resort to the following modifications:

The receiver is installed.
Exhaust pattern: 4-2-1.
Throttle valve: 54 -56 mm.
Sports camshaft.
Modification of the cylinder head (cylinder head) by sawing.
Lightweight valves.
440cc type injectors.

In addition to the considered method of transforming the power unit to increase dynamic performance, there are several more ways to tune a car of this model.

How much horsepower does the Priora have?

Now the car Lada Priora enjoys well-deserved popularity, not only among Russians, but also in the market of other European countries. And this is not easy, because Priora not only has a reasonable price, but also a huge number of both external and internal features, therefore it can compete with many cars in its own price sector.

The history of Priora has already spanned 7 years of successful production. Since 2007, it has been modernized many times - to date Lada Priora has the following features:

There are two engine modifications - with 8-valve and 16-valve engines, 1.6 liter capacity. Curb manual transmission gears and front drive Lada Priora, whose horsepower is 90 l and 98 l, depending on installed motor, indicates surprisingly very fast driving.

Highest torque, which was introduced using foreign production.

The environmental friendliness of the engine has increased.

The power of the updated version of the car was increased by 10%, due to this the question how much horsepower in Priora, has become more relevant, because an increase in power means an increase in the number of horsepower. The engine capacity also became larger in the new modification of the Lada, due to an increase in the piston stroke, while the cylinder diameter remained the same.

Units of power such as in Lade Priora – horsepower in principle, have practically gone out of use, but in Russia they are still common where engines are used internal combustion.

Since the calculation of horsepower after upgrading a car is often done in kilowatt/hours and they are also indicated in the car’s registration certificate, find out How many horsepower in Lade Priora it is possible, according to this translation: 1 l/s equals 735.5 W or 0.735 kW.

The developers also modernized the block’s cooling system and equipped the drive with an automatic tensioner. Trying to reduce mechanical losses, thereby reducing noise and vibration levels.

No matter how hard manufacturers try, faults can be found in a car of any brand, the most common problems Lada Priora engine:

1) Power reduction

2) Black exhaust

3) Difficulty starting the engine

4) Excessively high fuel consumption

The above malfunctions can be easily identified by the color of the exhaust: blue smoke may mean that the cylinder and pistons parts are significantly worn out; white smoke means that coolant has entered the combustion chamber, and black smoke indicates a malfunction of the control system.

Among car enthusiasts, the Lada Priora is considered the most controversial model of all the VAZ cars. It was based on the 1984 model platform. This car became a replacement for the VAZ-2110. The car turned out to be much more interesting than its predecessor. What engine does the Priora have? Let's get a look.

This car can easily compete inexpensive foreign cars. It has normal comfort and also good dynamics and reliability. Compared to previous models, the designers were able to significantly improve all handling indicators.

The car received a lot of unfounded criticism, especially the old 8-valve Priora engine was to blame. However, after the power units for them were replaced with new ones, they simply amazed car enthusiasts. If you look at it, it’s almost impossible to see much of a difference. But consumption decreased by 1 liter, power increased. The engine began to run much quieter than its ancestor. This is felt by both the driver and passengers. Just look at the photo of the engine to understand everything.

The unit operates smoothly at all speeds. If the “ten” required getting used to, then here you can drive with virtually no strain. This was achieved with improved design.

The Priora engine has a power of 98 hp. With. and a volume of 1.6 liters. This motor complies with Euro 3 requirements. Let's take a closer look at it.

Design

The power unit of Lada Priora cars provides torque, which is transmitted to the drives and wheels using the transmission system. This ensures the movement of the machine.

VAZ-21126 units are installed on cars. These engines are designed on the basis of VAZ-2112 engines. Engineers increased the engine displacement to 1.6 liters and also lengthened the piston stroke. The diameter of the cylinders remained the same.

Engine characteristics

We have a 1.6-liter sixteen-valve injection unit with Euro 3 standards. It is equipped with a distributed injection system controlled by an ECU. The cylinders are arranged in-line. The engine displacement is 1596 cc. see Maximum power - 72 kW. The torque produced by the engine is 145 Nm. It is assumed that 95 gasoline will be used as fuel. The fuel consumption of this unit is equal to 7.2 liters according to the passport. Maximum speed, which the Priora is capable of with the new engine - 183 km/h. The car can accelerate to 100 km in 11.5 seconds. Considering that you can install such an engine on a Priora, the price of which is about 35-100 thousand rubles, in almost any garage, it is definitely worth the money.

- materials

This unit is made of specially developed cast iron alloys with high strength characteristics, which made it possible to obtain the necessary rigidity and strength indicators. Coolant circulation channels now run along the entire height of the block. This made it possible to significantly improve cooling and also reduced the processes of deformation of the cylinder block due to overheating, which was not uniform. The channels for the passage of coolant are located in the upper part of the cylinder head.

Below you can find five supports for the crankshaft. The covers are attached using bolted connections. The bearing supports are equipped with liners. They are made of a special steel-aluminum alloy. They are used as bearings for the crankshaft. The middle support has special grooves. The latter contains thrust half-rings. They are designed to securely fix the shaft. This way you can avoid moving the part along the axis.

In comparison of this unit with model 2112, this unit has become slightly taller. You can see a photo of the engine.

Crankshaft and its features

This unit is made by casting from special alloys of high-strength cast iron alloys. In order for the part to be lubricated along with the connecting rod bearings, it has technological lubrication holes or channels. They are closed with plugs.

To reduce vibrations during operation, engineers used eight counterweights. They are located on the crankshaft. Radius crank mechanism now (in comparison with previous modifications) it has increased by 2.3 mm.

At the front of the device there is a pump for the oil system, as well as for the timing belt. The Priora engine is also equipped with a generator drive with a damper. At the rear there is a cast iron flywheel. A special gear rim made of steel is installed on it.

Connecting rods

These units are made from steel forging. They have caps on the heads at the bottom. They are produced by tearing them off from solid connecting rods. This way you can achieve more high performance accuracy. In the lower part of the connecting rod, liners with thin walls are mounted.

Pistons

The Lada Priora engine has many features. In particular, it is equipped with pistons made of special aluminum. Each of them has special rings in the amount of three pieces. The top two on each piston are compression rings, and the third, bottom one is the oil scraper ring.

The bottom has a flat shape, as well as four recesses for valves. At the same time, the recesses on the pistons are slightly larger compared to the previous modification of the engine. Cooling piston group performed with oil. To do this, engineers provided nozzles in the main bearing supports. These are tubes with balls on springs. When the engine is running, these parts allow oil to be supplied to the piston.

Cylinder head

The cylinder head is installed on top. This part of the engine is made by casting from special aluminum alloys. Its lower part has channels for coolant circulation. Mounted at the top camshafts. One is used for the intake valves, the other for the exhaust valves. The cylinder head on this engine is significantly different from the previous modification. Larger area flanges are used here, as well as spark plug well walls. The latter are now integral with the head.

Camshafts

These units are mounted on supports located in the upper part of the cylinder head. They are made by casting from high-strength cast iron. The Priora engine is equipped with hydraulic pushers, which automatic mode adjust valve clearances. The motor will not require its owner to adjust the gaps during its entire operation.

The unit has four valves per cylinder. The guide bushings and seats are firmly pressed into the cylinder head. Also, the first parts are equipped with locking rings. The guides are equipped with caps for removing oil.

Lubrication system

This unit is designed as a combined system. Oil is supplied both by splashing and under pressure.

Engine cooling system

It is presented in the form of a cooling jacket in the engine cylinder block and cylinder head. Just like in many other models from AvtoVAZ, there are other components in the SOD. This is a radiator, a coolant pump, and an expansion tank.

Nutrition

This part of the engine design is also no different. It, like previous models, consists of standard parts. The only differences are in the fuel rail. Now it has the shape of a pipe without backflow. It is made of stainless steel, and not aluminum, as before.

The injectors have also undergone changes. They are now slightly smaller. The pressure regulator has also changed. IN new version it is in the case fuel pump. The throttle body does not have a hole that in previous designs connected the air supply hose to the intake module.

Ignition

This system consists of individual coils on the cylinder head and spark plugs. All this equipment is controlled by the ECU. This innovation made it possible to abandon the high-voltage part, as well as make the system more reliable in operation.

Additional information about the engine

"Priora" (16 valves) was designed and developed together with the VAZ-11194 unit. Although these models had a difference in volume, in most of the designs and main components the two motors are the same. One of the main tasks that the developers faced was to achieve an increased resource. The engineers took the VAZ-21124 as the basis. Thus, the use of new technologies and solutions allowed designers to significantly increase the operating life.

Lubrication issue

Many car enthusiasts who have just become owners of this car do not know how to lubricate the engine. "Lada Priora" can work on various types lubricants

Today there is big choice materials for these motors. The main point here is to prevent mixing of transmission and engine oils. In Priora, these fluids work as efficiently as possible, and consumption is reduced to almost minimal levels.

For each specific power unit, the consumption will be different. However, even if you know what to pour into the engine, it is still better to consider the opinions of experienced car enthusiasts.

Before choosing an oil, it is better to first evaluate the color and thickness lubricating fluid. It is important that the thickness matches your engine. Often the engine characteristics include just such information.

You can check the quality of the oil right at home. To do this you will need a piece of toilet paper or a napkin. You need to drop a little onto a piece of paper or napkin. So, if the oil is absorbed quickly, then it is ideal.

Viscosity in winter and summer

So, what kind of oil should you fill into your VAZ Priora car? Different types of liquids can be poured into the engine of this machine. But first things first.

Many people ask how to change lubricants in different seasons. As they say experienced drivers, you need to select fluids according to the characteristics specified in the service book for the car.

In winter, to ensure that your Priora starts even in the most severe frosts, buy products with the OW index in the name. If the frosts are mild, then 15w-40 is ideal for a normal winter.

In the summer you can get by with absolutely any oil. It is important to make the replacement in time. This can save you a lot of money on repairs. Especially it concerns automatic boxes transmission

How much does the motor cost?

People often ask how much it costs to install an engine on a Priora. The price for a 16-valve unit will range from 35 to 100 thousand rubles, depending on the technical condition.

Rebirth

Recently, AvtoVAZ management announced the start of sales of updated versions of these cars. It will be a 1.8-liter engine. Small-scale production of these units is carried out by the company “Super-Auto”

Such machines have already been manufactured before. But now it will be a completely new engine. “Priora”, namely its power plant, will receive the name 21128. The torque will be 145 Nm, and what the power will be is still kept secret by the manufacturer. But it is already known that the dynamics of the new engine have improved slightly, but fuel consumption has remained the same.

The production of the restyled LADA Priora (“Lada Priora”) began in November 2013. They rolled off the assembly line of AVTOVAZ OJSC following cars of this family: VAZ-2170 - with a sedan body, VAZ-2171 - with a station wagon body, VAZ-2172 - with a hatchback body (five-door and three-door).

General characteristics

Initially, the car was equipped with an 8-valve engine from the VAZ 2114, about which car enthusiasts in practice know all the characteristics, in particular, what kind of service life it has in different modes. Therefore, the first “Priors” did not receive rave reviews from customers.

Subsequently, the car was equipped with its own 16-valve unit modification 21126 with a displacement of 1.6 liters and a power of 98 horsepower, which made the VAZ 2170 truly competitive. Dynamic performance has been improved, emissions into the environment and fuel consumption have been reduced. Appeared relatively recently updated version engine 21127 with a power of 106 hp. which has been installed on Priora since 2013. Comparative characteristics All three units are listed in Table 1.

Updates and Disadvantages

The table clearly shows how many horses the Priora had with the old power plant and how the power and torque changed as the update progressed. Here is a description of how they changed design features new units compared to old ones:

The number of valves has increased, there are 4 of them for each cylinder. It's no secret what a positive impact this factor has on engine performance. The filling of the cylinder with the combustible mixture is improved, and the chamber is efficiently emptied of combustion products ( exhaust gases), the operation of the unit becomes more stable, power increases while fuel consumption decreases.
The compression ratio is increased by increasing the piston stroke. New engine 21126 and 21127 now use gasoline with a higher octane number, but at the same time the efficiency of fuel combustion increases, which has a positive effect on power. It’s impossible not to notice how the working volume of the Priora’s engine has increased thanks to the increased piston stroke.
In modification 21127, compared to 21126, the intake manifold was modified. How this affected the engine performance of the Priora can be seen in the table. Power increased by 8 hp. in addition, performance at low and medium speeds has improved.
The new engines on the Priora have better environmental performance and lower fuel consumption. This was achieved through such improvements as modernizing the crankcase ventilation system and reducing the weight of the piston group. Now crankcase gases are burned more intensively in the cylinders and the emission of harmful substances into the atmosphere has decreased.
Over the many years of operation of VAZ cars, a definite opinion has developed that the power units of Zhiguli cars do not last until overhaul and 150 thousand km. Now, due to the use of new, higher quality components, the engine life has increased to at least 200 thousand km.

Despite the fact that the updated Priora engine is almost the most advanced domestic unit, it has its drawbacks. For example, when a timing belt breaks, the valves inevitably collide with the pistons and bend - this is its most serious drawback. How to eliminate it without waiting for trouble? It is necessary to replace the standard pistons with new ones, with special selections for the valves.

The remaining shortcomings are not so significant and they are usually associated with some kind of defect that can still be found on domestic cars. This could be increased noise from the operation of hydraulic compensators (often found on VAZ cars), an unexpectedly burnt gasket under the cylinder head, or floating idle speed. Or some unit of the attached equipment fails:

a drop in fuel pressure in the system leads to difficulty starting the Priora engine and loss of its power;
sensor malfunctions;
air leaks in the fuel tract through the pipes;
problems with the injector throttle valve.

For the first time, they decided to increase the power of the new Priora 21126 engine at the factory in order to create it sports modification. Camshafts with increased lift, a lightweight connecting rod and piston group were installed, and the intake and exhaust tracts were modified. This is how the first domestic sports unit appeared, which was put into production, and they began to install it on the Lada Granta Sport model.

The technical characteristics of the engine are as follows: engine power from the Priora has increased to 118 hp. torque - up to 154 Nm at 4700 rpm, fuel consumption also increased to 7.8 liters per 100 km with a combined driving cycle. We will give a number of recommendations on how to independently increase the power of Priora engines:

The easiest and most affordable way is to install an exhaust tract zero resistance. The essence of its work is to reduce the resistance of the path, as a result of which some of the power spent on overcoming this resistance will be released and become useful.
The same operating principle applies to the zero-resistance intake tract. Installing the receiver and throttle body at 56 mm will allow you to “breathe” more freely power unit, and your Lada Priora will become several horsepower more powerful.
Deeper tuning - new camshafts of a sports configuration, allowing the intake and exhaust valves to open more. This will give a noticeable increase in the agility of the car, especially in city conditions.
Replacing the standard valves and connecting rod-piston group with a lightweight one will again release some of the useful energy of the unit and add it to the main power. Here you can kill two birds with one stone: install pistons with recesses, thereby eliminating the possibility of them “meeting” with the valves when the timing belt breaks.
We should not forget about CHIP tuning. After major changes in the engine configuration, its operating mode will definitely improve, and in order to optimize it and adjust fuel consumption, you need to do a flashing.

Recommendations are given taking into account that the power plant is in good condition technical condition. If this is not the case, when tuning it is worth replacing worn parts and oil in order to get the desired effect from the changes. As a result of the above measures, the Lada Priora will receive an additional 20-30 hp. without reducing the resource.

How many horses can Priora have in addition to this? Quite a lot, there are capabilities and components to increase the power ultimately to 400 hp. This is due to a radical modification of the power plant: boring the cylinders, grinding the cylinder head, replacing the injectors and fuel pump with more efficient ones, installing four throttle valves and turbocharger.

We should not forget about modernization brake system. Such tuning will give excellent results in terms of power, but the engine life will be significantly reduced, and fuel consumption, on the contrary, will increase significantly.

Rules for long-term use

Surely every Priora owner wants to operate his car without unnecessary unexpected costs and is thinking about how to increase the life of the car. To do this you need to follow a few simple rules:

1. The power unit of the VAZ 2170, even without various improvements, has sufficient potential for “spirited” driving. But in order to save it and extend its life, such driving should be avoided. Smooth acceleration, maintaining a stable speed not only on the highway, but also in the city will help extend the life of the engine and save fuel and your own cash. The maximum permissible speed on the highway should be no higher than 120 km/h, the optimal is 100-110 km/h, and it is important to maintain stability.
2. Timely replacement is important Supplies, that is, oils in units, filters, spark plugs, high voltage wires, generator and timing belts, coolant. The interval between engine oil changes depends on its quality and chemical base. Mineral-based oils should be changed more often, synthetic oils less often. You should never determine the quality of motor oil by its color. If it has acquired a black tint, this does not mean that the oil is bad - it means that an excessive amount of combustion product deposits is formed in the engine. First of all, you need to find the source of the carbon deposits and eliminate it, and then change the oil.

The new engine must be properly broken in, and then the oil must be changed, following the manufacturer's instructions. When running in, avoid increased loads, sudden movements of the accelerator pedal, and do not exceed the speed specified in the instructions.
Always monitor the engine coolant temperature, check the operation of the electric cooling fan, thermostat and temperature sensor. Overheating is the main enemy of the piston group; every time the temperature is exceeded, it wears out intensely, and the life of the unit is sharply reduced.

"Lada Priora" - a modern high-speed domestic car, which will bring its owner a lot of positive impressions and driving pleasure, provided that the engine is cared for and properly modified and operated.
