What is the function of the Wuling Rongguang PCV valve?

[VictoriaAnn]

PCV valve function is to direct gases from the crankcase into the intake manifold through the PCV valve, with a small amount of air entering the intake manifold directly from the air filter via the PCV valve, preventing phenomena such as icing at the throttle, incomplete combustion, and worsened emissions. It also prevents blow-by gases from entering the atmosphere and avoids engine oil deterioration. Detailed information: Introduction: PCV stands for Positive Crankcase Ventilation system in Chinese. The PCV valve consists of a valve body, valve, and valve cover, and is generally installed between the valve rocker arm cover and the intake manifold. PCV valve inspection method: After reinstalling the PCV valve, remove the crankcase intake pipe from the air filter, lightly cover the pipe opening with a thin piece of paper. As the pressure in the crankcase decreases, the paper should be noticeably sucked towards the pipe opening. Additionally, after stopping the engine, remove the PCV valve and shake it by hand to check. If a 'click' sound is heard, it indicates the PCV valve is flexible and usable.
