M162 ENGINE MECHANICAL 1B1-17
Operation at Idling and Mid-Load
It show that the throttle valve (19) is closed or very partially opened and the vacuum pressure in intake manifold is high. The blowby gas in the crankcase in partial load flows into the intake manifold through the vent line (20) after passingthe air conditioner bracket (6) and the filter (4). The air reentered into the intake manifold will be dilluted on the flow
through the restriction hole (11) in the vent line (10). The circulated engine oil is separated at the air conditioner bracket (6) and then returns into the oil pan through thedrain pipe (7). The vacuum pressure generated at the crankcase sucks fresh air from intake air line(13) through the air admissionand vent connection (17,18). The fresh air prevents engine oil from being contami-nated and the air admission and vent connection (17,18) is designed to control the rapid pressure changes in intakeair line (13).
Operation at Full-Load
The throttle valve (19) is fully opened. All the blowby gases flow into the intake air duct (13) after passing through the oil separator (15,16) of the cylinder head cover (14) when fully loaded. This dilluted air will be supplied to the combustion chamber through the intakemanifold (12).
