6.5. System of ventilation of a case (PCV)
|
The system of ventilation of a case (PCV) reduces contents of carbohydrates in the fulfilled gases at the expense of removal karterny паров. It is carried out by means of circulation of the gases which have broken in a case and their direction through an air purifier in the inlet pipeline. |
|
Such system PCV is isolated. The gases which have broken in a case arrive in an air purifier or an air inlet at the expense of pressure in a case. On the majority of models mixing of gases with fresh air or passing of gases through a dozhigayushchy trap as it becomes in usual systems is not applied. On these models it is not established ordinary PCV valves - simply hoses. Disconnect from a cover of a head of cylinders PCV hose. |
|
The main components of PCV system are hoses which connect a cover of a head of cylinders and the case of a throttle or an air purifier. If there are abnormal working conditions (such as problems with piston rings), the system is calculated on sending superfluous amount of the broken gases on the pipeline of ventilation of a case in admission system that gases were used in normal process of combustion. It is expedient to check surplus of products of burning from the karterny gases circulating on hoses and unions - they can periodically cork system and cause increase in the block of cylinders of pressure |
|
As in these models the filtering element is not used, it is expedient to check PCV system channels on a blockage shlamy and combustion products. |
