Toyota RAV4>> The monitoring system and decrease in toxicity of the fulfilled gases>> System of compulsory ventilation of Carter (PCV)

Fig. 7.25. The scheme of compulsory ventilation картера: 1 – valve PCV; 2 – картерные gases; 3 – fresh air


The system of compulsory ventilation картера provides отсос from картера картерных gases and fuel steams in the inlet pipeline of the engine therefore pressure increase in картере because of penetration into it of the fulfilled gases and their emission in atmosphere (fig. 7.25 is excluded). Karternye gases mix up with fresh air and through the valve of compulsory ventilation картера move to an inlet collector.
The basic components of system of compulsory ventilation картера are the valve, the filter and vacuum hoses.
For support of frequency of rotation of idling valve PCV limits a passed stream, when vacuum in an inlet collector the high. If break of the fulfilled gases in картер the engine big, for example, at deterioration of piston rings, the system of compulsory ventilation картера directs картерные gases to the air filter where they are burnt further in engine cylinders.
Check of the valve of compulsory ventilation картера is resulted in section 2.
