UAZ vehicles are equipped with both types of engines: petrol and diesel. The latter type has a motor, which, according to its characteristics, is one of the most powerful internal combustion units on the domestic market. The Ulyanovsk Automobile Plant produces several series of engines that have been modified from four-cylinder engines. Consider the UAZ diesel engine in more detail.
Characteristics of the UAZ diesel engine
The installation of this type of engines has become a new stage in the development of the Ulyanovsk automotive industry: more opportunities, improved parameters and functionality of the car, more perfect dynamics and work in general. If we consider the ZMZ-5143 motor, then its volume is slightly more than two liters. It is fast enough, equipped with a perfect gas recirculation system and turbocharging. It is he who is put on UAZ-Patriot cars.
UAZ diesel engine parameters
Let's considerengine parameters. It has a direct injection system with mechanical control. The cylinders are arranged in one row, vertically. Their work is done in the order of first-third-second-fourth. The crankshaft turns to the right. Power is ninety-eight horsepower.
The UAZ diesel engine is equipped with pin glow plugs. The gearbox starter has a remote start, and the fuel system is distributive in its type. Mechanical pump controller.
There is a specialized lubrication unit in the cooling system, which is a water-oil exchanger. It is located between the cylinder block and the oil filter. The crankcase contains an oil pump with one section.
The cooling system is of a closed type with the possibility of forced circulation. The mass of the engine without refueling is about two hundred kilograms. The volume of the filled engine increases by about ten liters.
The nuances of a diesel engine in UAZ
The UAZ diesel engine needs warming up in the cold, and in a good way. When starting the car, if the temperature outside is below zero, it is recommended to wait a while when turning the key to the first position. This is done to warm up the fuel filter. Before starting the engine in full operation, it is necessary to let it run for a short time in low power mode. To break in the engine, you need to drive about three thousand kilometers.
The UAZ diesel engine needs to comply with certain modes,which will increase its service life.
It is not allowed to overheat, which must be monitored at all times by the temperature gauge on the instrument panel. If you give an engine that is not fully warmed up to the end, high speeds will lead to an increase in fuel consumption and faster wear of engine parts.
It is also necessary to observe the terms of inspection indicated in the service book. In addition, use only the oil and antifreeze specified in the same book.
Do-it-yourself installation of a diesel engine on a UAZ
Installing a diesel engine in a UAZ is not a very difficult task. You can do this work on your own.
Before removing the engine, it is necessary to drain the antifreeze, disconnect all pipes, remove the shutters with the radiator. It would be nice if the hood cover was also removed, as it interferes with the easy removal of the motor.
The next step is to remove all wires and tubes that are directly connected to the motor. These include a muffler, universal joints, cables on the handbrake and more. Then the gearbox is unscrewed and removed, the wires are disconnected from the generator, the filters with the generator and the fuel pump are unscrewed. All hoses are removed from the stove and radiator.
Removing the old motor and installing a new motor
After disconnecting from the engine all parts suitable for it, you can remove it. The replacement of the UAZ engine with a diesel one should be carried out by severalpeople, since the motor weighs about two hundred kilograms. For this purpose, it is best to involve four to five people. It is advisable to hook the motor onto a cable and get it out of the cabin on the passenger side.
It is also necessary to install a diesel engine on the UAZ with the help of five people, in the same sequence in which it was removed. All the necessary units are connected to the motor in the reverse order - a generator, a gasoline pump, and so on. All wires, pipes and radiator are installed back. Then the gearbox and clutch are installed. The muffler is screwed on, and finally the hood cover is placed.
Thus, it is clear that putting a diesel engine on a UAZ is not as difficult as it seems at first.
Diesel engine malfunctions and features of its disassembly
First, consider the reasons that will be a signal to disassemble the engine:
- increased oil consumption;
- incomprehensible smoke from the motor;
- drastic increase in fuel consumption;
- unusual noises;
- compression drop.
Having identified the reasons, it is necessary to start repair work. Installing a diesel engine on a UAZ requires it to be sorted out every time the performance parameters deteriorate. However, you should take into account the fact that some parts can be reused in the future.
When disassembling the motor, it is cleaned of dust and dirt, burnt oil. After disassembling it, they begin work on cleaning carbon deposits and degreasing parts of the engine. If they are under renovationare replaced, only new parts should be used, preferably from the same manufacturer as the unit itself.
Diesel engines have one distinctive feature - if the breakdown is not repaired in time, this can later lead to serious malfunctions or very rapid wear of parts, which ultimately will lead to the final breakdown of the entire unit. Malfunctions in the operation of the motor, similar to gasoline engines, are detected using computer diagnostics.
Finally, we will give recommendations on which brands of engines are suitable when installing a diesel engine on a UAZ. Experienced drivers of domestic SUVs are advised to install a diesel engine from a Ford Sierra car. A good option would also be a motor from Mercedes.
