Operation at Idling and Mid-Load
lIt 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 passing
the 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 the
drain pipe (7).
The vacuum pressure generated at the crankcase sucks
fresh air from intake air line(13) through the air admission
and 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 intake
air line (13).
Operation at Full-Load
lThe 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 intake
manifold (12).
