System of a retsirkulyatsiya of the fulfilled gases (EGR system)

The fuel system of the diesel engine is equipped with system of a retsirkulyatsiya of the fulfilled gases (EGR system), allowing to lower in the fulfilled gases the content of oxides of nitrogen (N0x) dangerous to environment. For this purpose the part of the fulfilled gases moves back in chambers of combustion of the engine that reduces temperature of combustion and, as a result, the content of harmful substances.

The system copes the DDE block which regulates amount of injected fuel and processes signals of the sensor of a pedal of gas, the sensor of number of turns, the sensor of atmospheric pressure and temperature of cooling liquid. The control unit via the vacuum valve regulates a vacuum impulse to the EGR valve and watches the correct dosage of a retsirkulyatsiya of the fulfilled gases. The EGR valve is in a final collector. At low temperature of cooling liquid and need of increase the engine capacities which have fulfilled gases are not recycled. The system of a retsirkulyatsiya of the fulfilled gases does not demand leaving.
