The power supply system of the carburetor engine consists of a fuel tank, the fuel pump, the carburetor, the air filter and топливопроводов. The carburetors established on cars, can be single-chamber and two-chamber. The fuel pump with a mechanical drive from a camshaft at engines in working volume of 1,1 and 1,3 l, and at engines in working volume of 1,6 and 1,8 l – from an intermediate shaft.

The air filter with a dry replaceable paper element is supplied with the automatic device for adjustment of the air temperature, submitted to the engine.

The part of engines is equipped with system вспрыска fuels. This system consists of a fuel tank, the fuel pump established near a fuel tank under the bottom of the car, and actually systems вспрыска fuels of production of Bosch or Volkswagen firm. Fuel is continuously sprayed by a nozzle in an inlet pipe where mixes up with air, and moves in the cylinder when the inlet valve will open.

The fuel tank, the fuel pump of a high pressure (TNVD), nozzle, fuel and air filters belong to fuel system of the diesel engine and топливопроводы. In the diesel engine fuel вспрыскивается nozzles directly in cylinders at the end of a compression step. Necessary pressure creates the fuel pump of a high pressure. The part of diesel engines is equipped with turbokompressor, these engines are called as engines with a turbo-supercharging. Turbokompressor allows to submit to the cylinder bigger amount of air in time while the inlet valve is open. Means, in the cylinder it is possible вспрыснуть bigger amount of fuel and as a result to raise engine capacity.
