PETROL ENGINES

In carburettor engines внутрикартерные gases дожигаются in the chamber of combustion of the engine at the expense of a stream redirection in soaking up collector. Feature of system on carburettor 4-cylinder engines is use дросселирующего a jet screwed in soaking up collector. At widely opened throttle заслонке the part внутрикартерных gases arrives in the air filter through a back part of a cover газораспределительного the mechanism.

On 6-cylinder engines and on 4-cylinder engines with system of injection of fuel the ventilation valve картера which operates a stream depending on depression degree in a soaking up collector is applied. At high depression the valve limits a stream in soaking up collector. A part of gases перенаправляется through a ventilating tube картера in the air filter and in the combustion chamber.

DIESEL ENGINES

The system of ventilation of the closed type provides a stream direction внутрикартерных gases in the combustion chamber through the valve and the air filter.

In system the control valve is in addition provided. At the big turns of the engine the valve diaphragm is closed also gases go directly to soaking up collector. At small turns the valve diaphragm is opened also a part of gases goes back in картер.

Care of system consists in periodic check of a condition of the valve of ventilation and a condition of hoses.
