System of the operated ventilation of a case (PCV)

The PCV system serves for decrease in issue in the atmosphere of hydrocarbonic connections due to removal of crankcase gases. The purge is carried out by circulation of the fresh air arriving from the air cleaner through a case in which it mixes up with the collected evaporations and the gases which broke from combustion chambers and is removed via the PCV valve in the inlet pipeline.

The PCV valve, the filter of a purge and set of the vacuum hoses connecting the listed devices to the engine are among the main components of system.

For the purpose of maintenance of stability of turns of idling the PCV valve blocks a purge stream at deep depression in the inlet pipeline. In case of violation of serviceability of functioning of the engine (as, for example, in case of problems with piston rings) the system makes withdrawal of excess of crankcase gases through a ventilating tube in the air cleaner.

The description of procedures of check and replacement of the PCV valve is provided in the Head Routine maintenance.
