Operation at Idling and Mid- Load
DThe throttle valve (6) is closed or very partially
opened, and the vacuum pressure in intake manifold
is high.
The blow-- by gas and the fresh air that is additionally
supplied through the vent connection (D) in the crank-
case in partial load gets supplied to the combustion
chamber from the crank chamber (12) through the oil
separation chamber (11), air -- conditioner bracket
(10), vent line (9), and restrictor (7) mounted to the
cylinder head.
The circulated engine oil returns to the oil pan through
the oil return pipe (13) at the bottom of oil separation
chamber (11).
The fresh air gets supplied to the crank chamber (12)
through the HFM sensor (1), intake air duct (4), vent
line (5), oil separation chamber (3), chain housing
(17), and the timing gear case cover (15).
The additional supply of the fresh air is needed to pre-
vent from forming the residues of the engine oil.

Operation When Full- Load at Partial Load
DThe throttle valve (6) is partially opened or fully
opened.
The air flows very rapidly through the vent line (5) s
connection (D) and the intake air duct when full-- load
at partial load.
Consequently, most of the low-- by gases are supplied
to the combustion chamber through the timing gear
case cover (15), chain housing (17), oil separation
chamber (3), vent line (5), throttle valve (6), and in-
take manifold (8).
