What is the composition of pvc valve?

PCV valve is a part of PCV, which consists of valve body, valve, bonnet and spring. PVC crankcase forced ventilation, that is, we often say that the oil pan active ventilation control system; It mainly plays the role of guiding the gas in the crankcase into the intake manifold through the PVC valve, which can avoid the problems of throttle freezing and insufficient combustion.

The function of pvc valve in automobile is to adjust the amount of oil fume caused by crankcase ventilation system entering the air intake system. When the engine backfires, the ventilation can be cut off immediately, so as to prevent the crankcase from exploding and other faults.

The failure of pvc valves in automobiles will have the following effects on automobiles:

1. When the engine rotates, it will tremble and vibrate, the idle speed will be unstable, and a large amount of white smoke will be emitted from the exhaust pipe;

2. Because it is in the crankcase, of course, if it is broken, it may affect its internal corrosion, accelerate wear and further reduce the service life of the engine;

3. The engine is not easy to start and the acceleration is weak;

4.4. The damage of PVC valve will also affect the sludge that is easy to precipitate and block. The blockage of oil sludge will increase the pressure of crankcase, and make the oil and gas in it flood into the air filter, which will eventually cause pollution and damage to the air filter.
