GENERAL INFORMATION

On all models the system of collecting karterny gases, the catalytic converter, system of a retsirkulyatsiya of exhaust gases and collecting system паров fuels is established. On some models the system of additional supply of air for decrease in toxicity of exhausts at engine warming up is established.

COLLECTING SYSTEM KARTERNYKH OF GASES

This system serves for collecting karterny gases and паров oils from a case of the engine and their direction to inlet highways of the engine for burning in the subsequent steps of operation of the engine.

SYSTEM OF DECREASE IN TOXICITY OF EXHAUSTS

For decrease in toxicity of exhausts on all models the catalytic converter is established. Information from the oxygen sensor established in a final collector or a reception pipe of an exhaust system, is used for exact adjustment of structure of a fuel mix.

COLLECTING SYSTEM PAROV OF FUEL

This system serves for collecting паров fuels from a fuel tank in the special coal filter. From where they then go to inlet channels of the engine for the subsequent burning in the course of normal operation of the engine.

RETSIRKULYATSIYA'S SYSTEM OF EXHAUST GASES

This system serves for the direction of a part of exhaust gases to inlet highways of the engine to lower the contents WITH in exhaust gases. The valve of system of a retsirkulyatsiya is supervised by the electronic control unit operation of the engine.

SYSTEM OF ADDITIONAL SUPPLY OF AIR

The electric fan forces air in a final collector under certain conditions operation of the engine. It improves combustion of hydrocarbons and increases temperature of exhaust gases. As a result of it the catalytic converter gets warm to necessary temperature for neutralization of exhaust gases quicker.
