EXHAUST SYSTEM
Operation at Idling and Mid- Load
The 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), airconditioner 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 prevent from forming the residues of the
engine oil.

EXHAUST SYSTEM
Operation When Full- Load at Partial Load
The 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 intake manifold (8).
