What is the purpose of Positive Crankcase Ventilation System

The positive crankcase ventilation (PCV) system vents harmful blow-by fumes from the engine crankcase into the engine air intake for burning with the fuel and air mixture. The PCV valve limits crankcase blow-by gas to the fresh air intake to suit the engine demand and serves to prevent combustion from backfiring into the crankcase. Thus, the benefits from the PCV system include the ability to:
• Maximize the oil cleanliness by venting moisture and corrosion from the crankcase.
• Protect against excessive crankcase pressure.
• Automatically regulate the ventilation system air flow to the engine air intake as required by engine operating conditions.
