Positive Crankcase Ventilation: Description and Operation
Description
DESCRIPTION
A "closed" crankcase ventilation system is used to provide a more complete scavenging of crankcase vapors. Fresh air from the air cleaner is
supplied to the crankcase, mixed with blow-by gases and then passed through a crankcase ventilation valve into the intake manifold.
