Device of system of compulsory ventilation of a case
The system of compulsory ventilation of a case is intended for decrease in the content of hydrocarbons in engine emissions at the expense of a purge of a case of the engine c by the subsequent suction of vnutrikarterny gases. The fresh air which is selected from the air filter, mixes up in internal space of the engine with vnutrikarterny gases and goes through a zolotnik of system of ventilation for reburning in engine cylinders.
The main components of system are the zolotnikovy device, the channel of selection of air and connecting hoses.
For maintenance of steady operation of the engine the zolotnikovy device which rummages inflow of a mix of vnutrikarterny gases at low depression on the soaking-up highway idling serves. At violation of normal operation of the engine (for example, at wear of piston rings) the vnutrikarterny gases which were formed many go through a ventilating pipe back to the air filter for reburning in the combustion chamber.
The mix of gases and air arrives in the butterfly valve chamber. In area near a butterfly valve later time resinous deposits are formed. It is necessary to delete these deposits periodically.
