Positive Crankcase Ventilation: Description and Operation
At Upper-Part Load to Full Load
The Blowby gases flow at upper part load and at full load out of the front of the crankcase (1) along the right intake duct (2) into the oil separation
chamber (12a) of the right cylinder head cover (12), along the ventilation line (5) into the intake manifold (10) and from there to the combustion
chambers.
Entrained engine oil flows through the oil separation chamber (12a) and the downstream syphon (13) into the oil separator (9) in the right cylinder head.
The oil separator (9) with rubber funnel (7) defoams the entrained engine oil.
