Operation at Idling and Mid-Load
lThe 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 crankcase 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 prevent
from forming the residues of the engine oil.

Operation When Full-Load at Partial Load
lThe 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).
