ABSTRACT:
An induction system for a multicylinder reciprocating internal combustion engine includes cylinder 8, cylinder head 10 having at least one intake poppet valve 12, and at least one exhaust poppet valve 14, with the induction system further including a crankcase ventilation system 26 for conducting gases from the crankcase of the engine to the cylinder head, and a PCV passage for introducing crankcase gases directly into at least one of the engine's intake ports 18. In the case wherein multiple intake valves and ports are used, PCV flow may be introduced through one port, with recirculated exhaust gas being introduced through a second intake port.
