id0116q1153200
Purpose, Function
• The PCV valve prevents release of blow-by gas (unburnt gas) into the atmosphere.
• The PCV valve is open/closed by the intake manifold vacuum.
Construction
• The PCV valve is located on the oil separator.
• The PCV valve consists of a spring and valve.
Operation
• When the valve is pulled by the intake manifold vacuum, blow-by gas flows to the intake manifold.
• The blow-by gas flow amount is determined by the balance of the intake manifold vacuum and the spring force.
