Crankcase ventilation system for outboard motor |
摘要 |
A ventilation system is provided for an engine crankcase of a marine outboard motor to distribute blow-by gas generally equally to each cylinder while minimizing the size of an intake silencer of the system. The intake silencer includes a first expansion chamber into which the blow-by gas is introduced from a blow-by gas camber attached to the cylinder head. The blow-by gas diffuses and mixes with ambient air which is drawn into the first expansion chamber through an inlet port of the induction system. The air/blow-by gas mixture is then drawn into a second expansion chamber where it distributes generally evenly before induction into a charge forming device.
