System of operated ventilation картера (PCV)

The general information

The scheme of movement of a stream картерных gases in the engines equipped with system PCV of a typical design


System PCV (address to an illustration above) serves for issue decrease in atmosphere of hydrocarbonic connections at the expense of a conclusion from the engine картерных gases. The block purge is carried out by prorace of fresh air arriving from an air cleaner through картер in which it mixes up with the collected evaporations and broken of chambers of combustion by gases and deduced through valve PCV in the inlet pipeline.

Valve PCV, air inlet and the complete set of the vacuum hoses connecting listed devices with the engine concern number of the basic components of system.

For the purpose of maintenance of stability of turns of idling valve PCV blocks a purge stream at deep depression in the inlet pipeline. In case of infringement of serviceability of functioning of the engine (as, for example, at wear process of piston rings) the system makes surplus tap картерных gases through a ventilating tube back in an air cleaner and their reburning in combustion chambers.

Receipt картерных gases in the engine is carried out through cases of a throttle which starts to become covered in due course by tarry adjournment, in particular around an arrangement throttle заслонки. In view of told, it is necessary to make cleaning of the case of a throttle from time to time.

Check

 PERFORMANCE ORDER

1. For check of serviceability of functioning of its valve PCV it is necessary to liberate from the rubber landing plug and to shake. The serviceable valve at stirring should publish the noise proceeding from запорной of a needle, – in case of need make replacement клапанной assemblages.
2. Start the engine on single turns and press a finger to an aperture in the valve, – in assemblage depression should take place. If depression is not felt, at first check up passableness of a vacuum hose, then (if the hose is perfectly in order) replace the valve.

Replacement

 PERFORMANCE ORDER

1. Having pulled vertically upwards, take the valve from the rubber landing plug. Estimate a plug condition, in case of need make replacement.
2.Если the valve is hammered by tarry adjournment, the probability of infringement of passableness of a connecting hose is not excluded also, – remove a hose and wash out its solvent.
3.Промыв a hose, check up it on presence of signs of ageing of a material and mechanical damages. Track reliability of fixing of a hose on reception unions.
4. In case of need make valve PCV replacement.
