What is the function of automobile pvc valve?

The function of automobile pvc valve is as follows:

1. The PVC valve on the automobile is a device on the forced ventilation system of the crankcase of the automobile engine, which consists of a valve body, a valve, a valve cover and a spring.

2. Its main function is to introduce the gas in the crankcase into the intake manifold through the PCV valve, and a small amount of air directly enters the intake manifold from the air cleaner through the PCV valve.

3. This can avoid the phenomena of throttle icing, insufficient combustion and emission deterioration. , and can prevent blowby gas from entering the atmosphere and prevent engine oil from deteriorating.

Influence of automobile pvc valve failure on automobile;

1, the engine will shake when running, the idle speed will be unstable, and a lot of white smoke will be emitted from the exhaust pipe.

2. Because it is in the crankcase, if it is broken, it may lead to internal corrosion and accelerate wear, thus further shortening the service life of the engine.

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

4. Damage to the pvc valve will also lead to sludge easy to precipitate and block, which will increase the crankcase pressure and make the oil and gas in it flow back to the air filter, which will eventually cause pollution and damage to the air filter.
