1B2-18 M161 ENGINE MECHANICAL 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 crankcase in partialload 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.
