ABSTRACT:
A clear base ventilation system for an internal combustion engine includes an air-oil separator. Blowby gas from the engine crankcase is drawn into the inlet of the separator in a swirling cyclonic motion so as to force any oil entrained in the blowby gas to impinge on the walls of the inlet and drain back into the crankcase. Blowby gas is then drawn into a baffle which further removes any entrained oil in the blowby gas as the gas flows therethrough. An outlet chamber exists at the end of the baffle and has a volume of space substantially greater than the volume of space in the baffle such that blowby gas flowing out of the baffle reduces in speed, thereby allowing any further entrained oil to separate from the blowby gas. Substantially oil-free gas is then introduced to the air induction system of the engine.
