4.1. System of ventilation of a case (PCV)

The valve of system of ventilation of a case copes the depression created in an inlet collector at operation of the engine.

At operation of the engine on frequency of rotation of idling, the valve is open slightly therefore a small amount of karterny gases is taken away in the resonant chamber and further дожигается in engine cylinders.

At increase in frequency of rotation of the engine, extent of opening of the valve therefore the amount of karterny gases which is taken away in the resonant chamber and further дожигается in engine cylinders increases increases.
