Positive crankcase ventilation
The crankcase ventilation system uses the depression created in the air intake to draw vapors from the crankcase through the engine where they are burnt with the fuel/air charge.
By doing this, any build-up of pressure inside the crankcase is avoided, reducing blow-by and potential oil leakage problems, while still reducing emissions into the atmosphere.
