What is a vehicle PVC valve?

[DiKennedy]

The PVC valve in a vehicle is a component of the engine's crankcase forced ventilation system. Here is an introduction to the PVC valve in vehicles: Components of the PVC valve: It consists of a valve body, valve, valve cover, and spring. Main function: It directs gases from the crankcase into the intake manifold via the PVC valve, with a small amount of air entering the intake manifold directly from the air filter through the P valve. Additional functions: It helps prevent throttle icing, incomplete combustion, and worsening emissions, while also preventing blow-by gases from entering the atmosphere and keeping the engine oil from deteriorating.
