The system of compulsory ventilation картера (PCV) serves for reduction of emission of hydrocarbons by tap of steams from картера the engine. It is carried out by giving of atmospheric air from the air filter in картер the engine where it mixes up with gases available there and then comes back through the system valve in an inlet collector.
The basic details of system PCV is a valve of system PCV, hoses for atmospheric air and the vacuum hoses connecting details of system with the engine.
For maintenance of normal work of the engine idling system PCV valve blocks a stream in the presence of high depression in an inlet collector. At infringements in work (for example, at defects of piston rings) the system serves for tap more a significant amount of the broken gases through an aperture for ventilation картера in the air filter, than it happens at a compression normal amount. |
