System of operated ventilation of a case (PCV)

 PERFORMANCE ORDER

1. The PCV system serves for decrease in issue in the atmosphere of hydrocarbonic connections at the expense of a conclusion from the engine of karterny gases. The purge of the block is carried out by pro-race of fresh air arriving from an air purifier through a case in which it mixes up with the collected evaporations and broken of chambers of combustion by gases and deduced via the PCV valve in the inlet pipeline.

2. The PCV valve, the filter of a purge and a set of the vacuum hoses connecting listed devices to the engine belong to number of the main components of system.
3. 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, at wear process of piston rings) the system makes branch of excess of karterny gases through a ventilating tube back in an air purifier.
4. The description of procedures of check and replacement of the PCV valve is provided in Head of Control and routine maintenance.
