Solution: find an extended rod.

Solution: Write special firmware for the “tidy” so that the data on the speed and number of crankshaft revolutions correspond to reality

Advantages and disadvantages

The advantages of the UAZ Patriot diesel unit are:

  • ease of overcoming snow drifts, sandy and clay roads by an SUV;
  • the ability to equip the car with a massive cabin with a spacious interior and trunk;
  • long engine life, minimal maintenance.

Autodiesel Patriot has the following disadvantages:

  • strong vibration in the cabin;
  • frequent failure of the timing belt and oil pump;
  • The Russian version of the motor cannot withstand severe frosts and the battery quickly fails.

The advantage of the UAZ Patriot diesel installation is minimal maintenance.

The presence of a second tank can be considered both disadvantages and advantages. The advantage is the ability to travel for a long time without the need to top up fuel. The disadvantage is that after filling one tank, you need to drive up to the pump from the other side to fill the second tank.

What is the difference between gasoline and diesel engines?

The petrol version of the internal combustion engine (displacement – ​​2.7 liters, torque – 217 N*m) is installed on the Patriot. A heavy fuel unit with a displacement of 2.3 liters and a torque of 270 N*m is used, which has a positive effect when driving outside the city. The gasoline engine allows you to accelerate to 150 km/h, which is 15 km faster than a diesel engine.

Features of operating a diesel engine:

  1. In severe frosts, you cannot immediately start the engine: you must turn on the ignition for 3 minutes and wait until the fuel in the filter warms up, only then can you start.
  2. When running in the first 2500 km, it is necessary to operate the car, setting the minimum load on the engine.
  3. It is necessary to use high-quality fuel, not lower than Euro-3.

The diesel engine cannot be started immediately in severe frosts.

The service life of a diesel engine is longer than that of a gasoline engine. If the machine is used in extreme conditions, the service life is reduced.

How is a diesel engine serviced?

A diesel car requires special care:

  1. The engine oil on a diesel power unit is more contaminated than on a gasoline one. Therefore, you need to change the oil and filter more often.
  2. You need to choose the best fuel filter, replace it more often and refuel at high-quality gas stations.
  3. Check the operation of the glow plugs and, in case of malfunction, replace them promptly.

The main reasons for the malfunction of a diesel engine are fuel leakage and airing of the system. To prevent this, you need to monitor the tightness of the fuel supply system.

How much fuel is needed for 100 km

According to reviews from motorists, in the urban cycle the fuel consumption of a diesel UAZ is no higher than 12 l/100 km. The consumption of the gasoline version in the city can reach 20 liters. On the highway, at a speed of 80-90 km/h, the diesel model will require 8-9 l/100 km. In mixed mode – 10 l/100 km.

The fuel consumption of a diesel UAZ is no higher than 12 l/100 km.

Is it worth installing a Toyota engine on the UAZ Patriot?

“Patriots” from the Ulyanovsk Automobile Plant are often called “people’s” cars in Russia. And they fully correspond to this high title, including due to their relatively low price. However, every experienced motorist knows that Patriots have their own drawbacks, one of which is the not very reliable power unit from the Volga manufacturer. Low reliability is also confirmed by the fact that GAZ has already abandoned the plant’s products.

There are many ways to solve this problem. Some people simply turn a blind eye to it and continue to use their favorite car, but others do not want to put up with the problem and often install V8 engines from Toyota in their cars.

First, let's look at the main problems of the Patriot's stock engine. There are a few of them:

  • fairly high gasoline consumption (12 l / 100 km);
  • low power for an SUV (150 hp);
  • poor reliability (it can break at any time if you are unlucky with quality).

Motorists may encounter various problems while operating a car with ZMZ 409: burnt valves, cracks in the cylinder block

, destruction of pistons and much more. Drivers often attribute all problems to the low quality of consumables used in production and poor assembly.

The engine has not changed globally since 1997. Yes, it has repeatedly undergone modifications and upgrades, its volume and environmental standard have changed. However, overall quality has not increased much. Even the manufacturer of these engines themselves recommends overhauling their engines after 200 thousand kilometers, but many of its components often do not survive to the 100 thousand kilometer mark.

There are several ways out of this situation. First of all, you can try tuning the engine itself. But even after a certain improvement in the characteristics of the motor, it will still remain not very reliable. A much more effective way to fix problems is to replace the engine with a more powerful one.

The large Toyota 3UZ-FE engine is very popular among motorists who are inclined to recycle their vehicles. This is a real long-liver, the service life of which (according to reviews from car owners) sometimes reaches a million kilometers. Of course, it also has weaknesses and vulnerabilities, however, again according to reviews, any problems that arise are relatively easy to solve.

At the same time, this engine has very good characteristics: 282 hp. With. with relatively the same fuel consumption, which ranges from 10 to 14 liters per kilometer. In addition, after the replacement, drivers note improved driving dynamics on highways and better cross-country ability on bad roads.
