Positive Crankcase Ventilation (PCV) System
PCV System:
DESCRIPTION The PCV valve is operated by the
intake manifold vacuum. When the engine is running at idle, the PCV valve is slightly open and a small amount of blowby gas is drawn into the dynamic chamber to be burned. As the engine speed rises, the PCV valve is opened further, allowing a larger amount of blowby gas to be drawn into the dynamic chamber.
