The positive crankcase ventilation system is employed to prevent air pollution caused by blow-by gases being emitted from the crankcase.
This system supplies fresh filtered air to the crankcase through the air intake hose. Inside the crankcase, the fresh air mixes with blow-by gases, which then pass through the PCV valve into the induction system.
