What Does PCV Stand For?

PCV stands for Positive Crankcase Ventilation

PCV, or Positive Crankcase Ventilation, is an emissions control system used in internal combustion engines. It functions by redirecting blow-by gases—combustion gases that escape the cylinders—back into the intake manifold for reburning, thereby reducing pollutants. The PCV system helps lower hydrocarbon emissions, enhances engine efficiency, and prolongs engine life by preventing harmful pressure buildup in the crankcase.
