1. Crankcase emission control system
Hyundai Sonata / Sonata 2011 Owners Manual / Maintenance / Emission control system / 1. Crankcase emission control system
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.
