Operation When Full-Load at Partial Load

l

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).
