Positive Crankcase Ventilation System
WARNING: This page is about a different variant/trim than selected.
The positive crankcase ventilation (PCV) valve carries the blow-by gas to the turbocharger inlet of the intake system. According to the engine conditions, driving conditions and the pressure of turbocharger, it is different from the amount of blow-by gas. So, the PCV valve controls the amount of blow-by gas.
