VENTILATING DEVICE IN CRANK CHAMBER OF COMBUSTION ENGINE AND, ESPECIALLY, COMBUSTION ENGINE HAVING V-SHAPED CYLINDER STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a ventilating device in a crank chamber of a combustion engine capable of exhausting so-called blowby gas through a hole integrated with cylinder heads 7, 8 and a ventilating pipe linked to the hole and linking the ventilating pipe to a negative pressure reducing element, for example, an intake pipe at this time and having means 26, 28 for separating oil from blowby gas. SOLUTION: At least one of separate oil separation modules 26, 28 is arranged, and oil separation chambers 30, 31 formed in them have first opening parts 66, 68 for letting blowby gas flow into them and second opening parts 50 to 56 for returning separated oil into the cylinder heads 7, 8.
