New engine UAZ Patriot 150 hp will appear under the hood of an SUV soon. Another modernization of the well-known 409 engine allowed for a significant increase in power. Recall that now the 2.7-liter 16-valve engine with a chain drive on the Patriot develops only 135 hp, a little earlier it produced 128 Horse power.
The next modernization of the 4-cylinder aspirated engine made it possible to squeeze out not only more power. But also to create a competitive modern unit. You can find out about the state of the motor using the delphi ds150e diagnostic scanner connected via the OBD2 protocol connector. If for foreign cars, this has long been the norm, then for domestic cars such an opportunity to check the technical condition of the car appeared relatively recently.
The manufacturer itself proudly declares that the real power has increased to 160 horses, but this figure has been adjusted to the level of 150 hp, so that buyers do not have to pay an increased road tax. Today we will tell you how we managed to increase the power and what has changed in the well-known ZMZ 409, which is now called the ZMZ PRO.
Changes to the new engine UAZ Patriot 150 hp
- 1. The compression ratio was increased from 9.1 to 9.8
- 2. The valve lift was increased by 0.5 mm due to new camshafts.
- 3. Changed the valve timing.
- 4. Applied the new geometry of the exhaust system.
- 5. Used a new timing chain and piston group.
- 6. Raised the speed of maximum power from 4600 to 5000 rpm.
Perhaps the most pleasant circumstance, not only an increase in 15 horses, but also an increase in torque from 217 Nm to 235 Nm... In addition, if on the old version of the UAZ Patriot 409-06 engine, the maximum torque was available only from 3900 rpm, now this level has been reduced to 2600 rpm. That is, in order to drive normally with ZMZ PRO (409-051), you will not have to turn the engine at maximum speed, and this will significantly reduce fuel consumption.
It is the fuel consumption for the UAZ Patriot that is one of the significant disadvantages. By the way, it is logical to assume that increasing the compression ratio will require more quality gasoline however the developers new version 409th they assure that AI-92 gasoline is also quite suitable.
Characteristics of the UAZ Patriot ZMZ PRO 150 hp engine
- Working volume - 2693 cm3
- Number of cylinders - 4
- Number of valves - 16
- Cylinder diameter - 95.5 mm
- Piston stroke - 94 mm
- Power h.p. - 149.6 at 5000 rpm
- Power kW - 110 at 5000 rpm
- Torque - 235 Nm at 2650 rpm
- Compression ratio - 9.8
- Timing drive - chain
- Fuel type - gasoline AI 92
Moreover, buyers are promised not only a new motor with increased power, but also another modification of this gas-powered power unit. It's no secret that many owners of Patriots in our country independently convert the gluttonous 2.7-liter engine to gas engine fuel. True, the power of this version will drop to 143 hp. (227 Nm). A propane-butane mixture will act as an alternative to gasoline.
The main unit of any machine is the engine. Pickups, sedans, convertibles, buses, tractors simply cannot perform their direct duties without an engine. That is why great attention is paid to the motor when choosing a car, its maintenance and operation. In addition, this is one of the most expensive units. Replacing or repairing it almost always costs a lot of money, requires a lot of effort and time.
For an SUV, reliability and technical condition the engine is even more important. After all, a breakdown of an engine in a forest, a field, far from roads and people can end up really sad.
A bit of history
The first UAZ Patriot left the assembly line in 2005. It was really new UAZ incredibly modern in relation to past models. The manufacturer has positioned this machine as safe, reliable and powerful SUV... The design was good for 2005. And if you look not at the previous models, the design seemed perfect.
In October 2014, the new Patriot was introduced. He received rear stabilizer, touchscreen display, glued-in glass, more attractive looks, and the bumpers are now attached to the body. However, there were big security problems. Therefore, in October 2016, UAZ showed another update. "Patriot" received frontal airbags, even more attractive and modern appearance. The overall safety and soundproofing of the SUV has improved. Finally, the car got rid of the two fuel tanks that tormented all the owners.
What engines exist on the UAZ "Patriot"?
Throughout the first generation, a permanent 2.7-liter gasoline engine with a capacity of 128 horsepower was installed. In 2008, engineers added more and diesel engine a volume of 2.3 liters, the return of which was 114 horsepower. It was the Iveco F1A engine. It was installed during the production of Fiat Ducato cars in Russia. This motor was later removed. Since 2012, the ZMZ-514 turbodiesel has been installed. Because of this, the working volume of the engine decreased by 65 cubes. Thus, the improved UAZ Patriot engine received the 2.2d index. The same motor remained after the update in 2014. But the gasoline engine has undergone some changes. As a result, its official power was equal to 135 liters. with. On the newest UAZ "Patriot", heavy fuel engines are no longer to be found. The diesel engine was abandoned. The gasoline engine was left unchanged.
Diesel engine
Turbodiesel "Iveco F1A" was expensive, but really reliable motor... In addition, it allowed to reduce the Patriot's appetite to twelve liters per hundred kilometers of run in the city. A calm driver could get fuel and ten liters in the city. Not bad for a frame SUV. In addition, despite the lower power, when compared with a gasoline engine, it made the car much faster. The petrol version was lost after 80 km / h, while the turbodiesel easily accelerated to 120 km / h. This is due to the torque, which was equal to 270 N * m, against 218 "gasoline Newtons". The diesel also performed much better off-road. It helped to get rid of the turbo lag. Traction was always enough.
In 2012 diesel engine UAZ "Patriot" from the Italian manufacturer was replaced. Replaced with the infamous ZMZ-514. It was developed back in the 90s. Had a lot of engineering errors that affected reliability. Cracks in the cylinder head, valve disc hitting the cylinder, pipeline breakage high pressure and many other problems are still dreamed of in nightmares by owners of diesel "Patriots".
According to the engineers, most of the problems have been resolved. Changed suppliers of low-quality components, modified the engine together with Bosch. And so it turned out the same diesel reliable engine UAZ "Patriot". Reviews confirm this. Since mid-2012, when the Common Rail system was installed, the motor did not cause any particular problems for the owners. Moreover, in terms of driving qualities and characteristics, the UAZ Patriot engine powered by the ZMZ diesel engine almost completely coincided with the turbodiesel from Fiat Ducato. Despite this, the manufacturer has phased out the diesel engine since October 2016. Perhaps there was low demand, or maybe this engine was too expensive for the plant, but it is no longer possible to buy a new diesel "Patriot".
Petrol engine
The first generation of the Patriot received a 2.7-liter gasoline engine. Its power was 128 forces. After the 2014 update, the official power increased to 135 horsepower, and the maximum torque dropped by one N * m, from 218 to 17 N * m. However, when tested on a dyno, the factory cars of 2015 showed more than 140 forces. This engine went to UAZ from another 24 Volga, albeit with some changes. And in the "Volga" the declared engine power was 150 horses.
A car with this engine has always cost less in the showroom and on the used car market. The pluses include relative reliability. power plant... The engine in the UAZ "Patriot" has good maintainability, and spare parts for it cost almost nothing. This has always won over people who choose a Russian SUV, because repairing a diesel engine is several times more expensive. But you definitely won't save on gasoline. Less than 15 liters per hundred in the city is simply unrealistic for a gasoline "Patriot". If you stand in traffic jams, try to actively accelerate, then a flow rate of 20-22 liters per hundred kilometers is ensured. And if you consider that a car with this engine simply does not go (acceleration to 100 km / h is 19 seconds), then you have to turn this engine.
Gasoline engine problems
The childish appetite of the 2.7-liter UAZ Patriot engine is not its only problem. The open circuit plagued many SUV owners. In 2017, the manufacturer changed the supplier.It remains to be seen whether this will solve the problem.
Output
What is the ideal engine for the Patriot? Diesel from Iveco. You can walk 500,000 kilometers without any problems. Repairs are cheaper than the ZMZ diesel. You buy new car? There is simply no choice. The gasoline engine is very reliable, it is worth watching only the chain.
With a volume of 2.7 liters, it produces 128 hp. with a torque of 210 Nm. The second engine with which they sell today UAZ Patriot, this is a 2.2-liter diesel engine with 114 hp. at 270 Nm of torque. Diesel is also collected at ZMZ (Zavolzhsky Motor Plant). Today we will talk in more detail about these power units for a domestic SUV.
Gas engine Patriot, this is the ZMZ 409, which became the successor to the well-known 406 motor. Inline 4-cylinder 16-valve power unit with aluminum block and aluminum cylinder head. The engine has two overhead camshafts that move the valves by means of hydraulic lifters. That is, you do not need to manually adjust the valves on this motor. Injection injection allows the engine to comply with the Euro 4 environmental standard. There is a chain in the timing drive. It would seem that there could be more reliable, but it is the chain that is the most weak point motor. The constant complaints of the owners about the open circuit forced the manufacturer to abandon the use of Chinese hydraulic chain tensioners, replacing them with German ones. Further more detailed specifications this engine.

The fuel consumption of the gasoline Patriot is a separate topic, since in off-road conditions with the four-wheel drive, with the air conditioner running, the consumption can reach 25-30 liters per hundred. Therefore, to accurately determine real expense not possible, due to the huge number of concomitant factors affecting Patriot gas mileage.
Diesel engine UAZ Patriot ZMZ-51432, which is now installed on domestic SUVs, has recently been mastered. Prior to that, a 2.3-liter IVECO unit was installed under the Patriot's hood. The domestic motor gives out about the same characteristics. Power 114 HP with a torque of 270 Nm. Inline 4-cylinder 16-valve turbo diesel Common rail with injection "BOSCH" has an aluminum block and a block head. The timing drive is also a chain drive. Diesel is significantly more expensive than the gasoline version, therefore it is offered only in the most expensive trim levels. Diesel Patriots are not very popular despite significant fuel economy and increased torque. Further detailed characteristics of the turbodiesel power unit.

The main gift to all lovers of Russian SUVs this year will be presented by ZMZ in the summer on the assembly line of UAZ. new Patriot... The more modern UAZ-3170 will receive a new gasoline engine, which will replace the 2.7-liter unit, which is very gluttonous and not very dynamic. The new ZMZ gasoline engine will have a smaller working volume (rumored to be 2-2.4 liters), while the engine power will increase, and fuel consumption will be significantly reduced!
Two humps are only good for a desert ship. But an SUV is not a camel, the double-humped torque curve for its engine is not the best option... That is why I shuddered when my good friend Volodya Sharandin invited me to drive the Patriot along the ice track.
We passed, we know! To drive, when after the first burst the thrust drops to three thousand revolutions? Dubious pleasure. Even the next surge in the region of four thousand does not help. Yes, and high-speed exercises on the Ulyanovsk all-terrain vehicle seemed to me akin to off-roading on a passenger car.
But Volodya knows how to persuade and, frankly, never proposed stupid ideas. Moreover, he had not been to his homeland for fifteen years, and during this time he became a cool automotive engineer, complementing his Russian education with American and European. Today his strong point is civilized tuning in its own center. In general, I was intrigued: UAZ in its performance should be extraordinary.
Gave traction
The door slammed and I was driving the Patriot. Everything is familiar, only the engine sounds strange. Not louder, but the tonality has changed, and in better side... I like this song better than the old one. How about on the go?Here the moment is two hundred and seventy and the power is one hundred and eighty. Don't be shy, spin until you cut it off!
Sharandin urges me on, but you don't have to ask me for a long time. Gas to the floor! I didn’t drive such a Patriot - it accelerates very quickly! It became even scary: you have to get used to the brisk character, because the chassis and brakes are standard, but the agility is different. Vnatyag? And at the bottom, this Patriot is more convincing. Lucky exactly, without plugs. Especially after 1800 rpm.
A surprise awaits me on the track - a standard Patriot. Volodya provided for this "piano in the bushes" so that I could change from car to car - for comparison. Well, go ahead!First, a small motocross piece. You can't accelerate here: continuous hills with steep descents and ascents. Serial Patriot took all the slides - some in first gear, some in second. And in a car with a modified engine, you can drive differently: after a couple of climbs, I stop switching - there is enough traction, I go through the entire obstacle course in second gear.
The highlight of the program is the autocross track. Turning corners and appendixes, ice interspersed with snow porridge. The serial Patriot, with its weight and overall height, is well controlled on slippery road... Of course, we have to be active. I twist it at large angles - tea, the mechanism is not rack and pinion. In areas with loose snow, so as not to lose speed, I change from third gear to second. I switch often, but overall - bearable. To be honest, after this "race" I changed my opinion about the Patriot for the better, but did not get much pleasure. Still, a serial UAZ is not for drifts and drifts, storming turns with a fan is not his element.
Now - 182-strong car. Truly, there is never too much power and moment! The chassis is the same, but the ride is more pleasant and, most importantly, safer. Almost the entire track is in third gear, switching only in a couple of places. Now I understand why Sharandin invited him exactly: this Patriot is already controlled by gas - and you get pleasure from the process. Instead of oiling the steering wheel, you can actively use traction - the engine, one might say, pulls the Patriot out of the demolition.
Arrived in our shelf
At the base where Volodya is finalizing the cars, homework is already in store.Look, we managed to smooth out the humps, and not just raise the torque!
Sharandin lays out a printout of the external speed characteristics motor, filmed on the MAHA roller stand. Indeed, an almost flat shelf of 260–270 Nm in the range of 1800–4800 rpm. And the power is much higher: 182 hp. at 5200 rpm. The serial engine produces 134 hp, and the maximum 217 Newton meters - the same humps at 2500 and 4000 rpm. The most curious thing is that such results were achieved without opening the engine and, accordingly, without installing new shafts, pistons, connecting rods. Changed only inlet and.
Direct flow? Whom will you surprise with this! Everything is much more interesting than the primitive struggle against backpressure - here the intake and exhaust are coordinated.
Shelf alignment technology is as follows. First, a 3D scan of the engine compartment and the underside of the car. This allows you to evaluate the space in which new parts are to be placed. Then comes the calculation and design of iron.
The task is to boost the engine by improving the filling of the cylinders. To do this, work with air flows at the inlet and outlet and harmonize the wave processes in the engine.Then an exhaust manifold is made with pipes of equal length. The "spider" of the 4-2-1 scheme fit into the UAZ (the 4-1 variant cannot be placed in the engine compartment). That is, the pipes are first merged in pairs, and then they go into a single pipe. Next comes the modified resonator and muffler. Everything is stainless steel.
And also - a non-standard intake. The low resistance filter is placed in a cold zone where the air density is higher. Behind it is a diffuser and an intake pipe. Their diameters, roundings, dimensions are the result of calculations and experiments. After all, the air flow does not like a sharp change in direction, sharp contractions and expansions.
After assembling the components on the car, the fine-tuning procedure begins on the MAHA roller stand. The wheels are scored and the electronics plotted power and torque curves. In the initial version, telescopic pipes are used - by changing their length, the developer adjusts the characteristics. Volodya, although he is a race car driver in the past, prefers to rely not on high revs, but for a moment - such motors are much more convenient in everyday use. The Patriot is a very special case: improvements should not affect his all-terrain qualities. Squander cravings on low revs- means to ditch.
If it is possible to get a weighty additive due to "inhalation-exhalation", that is, inlet and outlet, why does the plant not do this?
Features of mass production do not imply individual selection of engine characteristics and work on "gold" technologies. There the average setting rules the ball. "Eternal" stainless steel release, playing with telescopic collector pipes, rejection of a filter box in favor of a filter of low resistance is the lot of small tuning firms. And they kill several birds with one stone.Moderate forcing does not affect. In this regard, working with a hitch is a much less risky business than disassembling the engine with the replacement of expensive parts. And, which is very pleasant, the price is not exorbitant. The modified intake-exhaust system costs about 50 thousand rubles - taking into account the installation and settings.
With the advent of new SUVs from UAZ the lineup domestic cars replenished with new copies (moreover, the UAZ Patriot engine is produced both in Russia and abroad). Only three types of engines are installed on SUVs (one of them is gasoline, the other two are diesel).
All engines installed on the UAZ Patriot comply with Euro-2, Euro-3 and Euro-4 environmental standards. One of the engines - foreign production(it was borrowed from the Fiat Ducato, the manufacturer is Iveco).
These engines are installed on the entire UAZ Patriot model range. In other words, when choosing a pickup truck, you can find three identical cars with different engines. Which one to choose is a personal matter. But before purchasing, you should study the features of each engine and find out what they are individually.
Gasoline engine UAZ Patriot
The power unit is produced by the Zavolzhsky plant (ZMZ), located in Nizhny Novgorod. It has injection system injection and full compliance with environmental standards Euro-2. ZMZ supplies these engines not only to UAZ, but also to Pavlovsky and Gorky automobile plants. Hence, we can conclude that in the case of repair, spare parts are very easy to find (and many people, when buying a car, look at this almost first of all).
With an engine capacity of 2.7 liters, fuel consumption in city mode is 14.5 liters, and when driving on the highway - four liters less. The engine power of the UAZ Patriot at 4400 rpm is 128 horsepower. The engine has two camshafts(for intake and exhaust valves).
The main task of the car is to drive confidently over difficult terrain. The engine load of the UAZ is much higher than that of any passenger car. Therefore, the engine uses high-strength steel parts (crankshaft and camshafts, engine block).
Diesel engines of UAZ
Diesel engines are of two types: domestic ZMZ and imported Iveco. The Russian model complies with Euro-3 environmental standards, while the Iveco engine complies only with Euro-2. Both engines are four-cylinder, cylinder arrangement: in-line, cooling system: liquid.
The Iveco engine has a working volume of 2.3 liters. Fuel consumption on the highway is no more than nine liters. Engine power at 3900 rpm is 116 horsepower. For the domestic consumer, the Iveco engine installed on UAZs will not cause difficulties in repair and maintenance.
Fiat cars, from which the engine is borrowed, are very popular in our country. Consequently, special problems with the presence necessary spare parts will not arise. In addition, UAZ with such an engine has a good power reserve.
Depending on the vehicle configuration, the engine, in addition to its main function, also performs auxiliary functions: this is a power steering drive and an air conditioning compressor. Even with particularly heavy loads while driving, all the auxiliary equipment of the UAZ Patriot will work without problems.
The second version of the diesel engine is the domestic ZMZ. With a volume of 2.25, it has slightly lower characteristics than the Iveco engine. Engine power - 113 horsepower at 3500 rpm. UAZ Patriot equipped with engine ZMZ, develops maximum speed 135 km / h and consumes 9.5 liters of fuel for every hundred kilometers on the highway.
In conclusion, we can conclude that in terms of fuel consumption, the most acceptable option is a diesel engine. But if you need a UAZ Patriot with the greatest power, and the price of fuel is in last place, then it is better to give preference to a gasoline engine.
