The main unit of any machine is the engine. Pickups, sedans, convertibles, buses, and tractors simply will not be able to perform their direct duties without an engine. That is why great attention is paid to the engine 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 and requires a lot of effort and time.
For an SUV, the reliability and technical condition of the engine is even more important. After all, an engine breakdown in a forest, field, far from roads and people can end really sadly.
A little history
The first UAZ "Patriot" came off the assembly line in 2005. It was truly a new UAZ, incredibly modern compared to previous models. The manufacturer positioned this car as a safe, reliable and powerful SUV. The design was good for 2005. And if you look at the previous models of the Ulyanovsk Automobile Plant, the design seemed perfect.
In October 2014, the new Patriot was introduced. It received a rear stabilizer, a touch screen, glued glass, a more attractive appearance, and the bumpers were now attached to the body. However, there were major security problems. Therefore, already in October 2016, UAZ showed another update. “Patriot” received front airbags and an even more attractive and modern appearance. The overall safety and sound insulation of the SUV has been improved. Finally, the car got rid of two fuel tanks, which so tormented all owners.

Since the 409 engine is used mainly in SUVs, there is no point in considering the option of building a powerful naturally aspirated engine on wide-phase camshafts. The main goal of UAZ owners is to make the engine low-powered and high-torque. The camshafts are standard, the head needs to be modified, the factory one is of very low quality, we go through the cylinder head and manifold channels, grind them, Garrett 17 turbine, manifold for it, intercooler, 440cc injectors, 63mm straight-through exhaust, set up.

What engines are there 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 also added a 2.3-liter diesel engine, the output of which was 114 horsepower. It was an Iveco F1A engine. It was installed during the production of the Fiat Ducato car in Russia. This motor was later removed. Since 2012, they began to install the ZMZ-514 turbodiesel. Because of this, the engine displacement decreased by 65 cubic meters. Thus, the improved engine of the UAZ Patriot received the index 2.2d. The same engine remained after the update in 2014. But the gasoline engine has undergone some changes. As a result, its official power became 135 hp. With. On the newest UAZ "Patriot" engines running on heavy fuel can no longer be found. Diesel was abandoned. The gasoline engine was left unchanged.
Diesel engine
The Iveco F1A turbodiesel, although expensive, was a truly reliable engine. In addition, it made it possible to reduce the Patriot’s appetite to twelve liters per hundred kilometers in the city. A calm driver could get ten liters of fuel in the city. Not bad for a frame SUV. Moreover, despite the lower power compared to a gasoline engine, it made the car much faster. The gasoline version was lost after 80 km/h, while the turbodiesel easily accelerated to 120 km/h. This is thanks to the torque, which was equal to 270 N*m, versus 218 “gasoline Newtons”. The diesel also performed much better off-road. A lower gear helped get rid of turbo lag. There was always enough traction.
In 2012, the UAZ Patriot diesel engine from an Italian manufacturer was replaced. Replaced with the infamous "ZMZ-514". It was developed back in the 90s. Had many engineering errors that affected reliability. Cracks in the cylinder head, a valve disc getting into the cylinder, a break in the high-pressure pipeline and many other problems are still the nightmares of owners of diesel Patriots.
According to engineers, most of the problems have been resolved. They changed suppliers of low-quality components, modified the engine together with Bosch. This is how the reliable diesel engine of the UAZ “Patriot” turned out. Reviews confirm this. Since mid-2012, when they began installing the Common rail system, the engine has not caused any particular problems for owners. Moreover, in terms of driving qualities and characteristics, the UAZ Patriot engine on the ZMZ diesel engine almost completely coincided with the turbodiesel from Fiat Ducato. Despite this, the manufacturer abandoned the diesel engine from 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.

UAZ Patriot, the new engine for the SUV for the 2017 model year, now meets EURO-5 environmental standards. In essence, this is a well-known 2.7 liter 4-cylinder 16 valve unit. Another modification of the ZMZ 409. This time a new version of the ZMZ-40906 is installed under the hood of the Patriot. The engine has become not only more environmentally friendly, but also more powerful. Engineers at the Zavolzhsky Motor Plant managed to increase power to 135 hp and increase torque to 217 Nm.
By the way, the UAZ diesel engine was temporarily abandoned in Ulyanovsk. Sales of UAZ Patriot with such an engine did not exceed a few percent. Despite the fuel gluttony, the majority of buyers choose the gasoline version.

Gasoline 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 decreased by one N*m, from 218 to 17 N*m. However, when tested on a dyno, the 2015 factory cars produced over 140 horsepower. UAZ inherited this engine from the 24 Volga, albeit with some changes. And in the Volga the declared engine power was 150 horses.
A car with this engine has always been cheaper in the showroom and on the used car market. The advantages include the relative reliability of the power plant. The engine in the UAZ Patriot has good maintainability, and spare parts for it cost almost nothing. This has always attracted people who choose a Russian SUV, because repairing a diesel engine is many 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 and try to actively accelerate, then a consumption of 20-22 liters per hundred kilometers is guaranteed. And if you consider that a car with this engine simply does not move (acceleration to 100 km/h is 19 seconds), then you will have to turn this engine.

The Patriot diesel unit has a problem with the 5-speed manual transmission, which does not allow it to take full advantage of the engine. When driving on the highway, the diesel engine simply lacks 6th gear. Although it is ideal for off-road use. By the way, the gearbox for a gasoline engine has a gear ratio of the main pair of 4.11, for a diesel engine it is 4.625. When purchasing, it is recommended to install a pre-heater, otherwise in winter there will be problems with starting this engine.
In September 2021, in Moscow, at the Crocus Expo exhibition complex, the International Exhibition of Commercial Vehicles Comtrans 2021 was held. At this exhibition, UAZ showed a new commercial vehicle, the UAZ-Profi, which was equipped with a new ZMZ-PRO engine.
New engine, this is naturally good (hopefully) reworked old ZMZ-409
After processing, the following characteristics : Power 149.6 hp. at 5000 rpm Torque 235.4 Nm at 2650 rpm Compression ratio 9.8
At this compression ratio, it is supposed to be filled with 95-octane gasoline. Which is not very good for commercial vehicles. But a Gas-Gasoline . This engine is abbreviated ZMZ-409052. The equipment is Italian, the brains are accordingly tuned to dual-fuel mode.
The single-row chain that broke on the Patriots was finally replaced with a double-row. (who remembers, the double-row chain was on EURO-3, they returned so to speak) The tension shoes went away and sprockets appeared again. INA hydraulic tensioners, OTHERWISE this chain will break too
