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 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
contaminated 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
•
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 intake manifold (12).
