Abstract
A positive crankcase ventilation system for an internal combustion engine (ICE) includes an engine crankcase, an intake manifold disposed in downstream gas flow communication with the engine crankcase, an air induction system disposed in upstream gas flow communication with the engine crankcase, and a vacuum pump disposed in gas flow communication between the air induction system and the engine crankcase. Operation of the vacuum pump facilitates air flow from the air induction system to the engine crankcase, and from the engine crankcase to the intake manifold.
