ABSTRACT:
A centrifugal oil separator assembly (36) mounts to the front cover (26) of an internal combustion engine (20) adjacent to the engine crankcase (34). The oil separator assembly (36) includes a first rotational member (42) that has turbo fan blades (52) and a second rotational member (56) that has centrifugal fan blades (60) and air seal grooves (66). A driven pulley (44) causes the oil separator assembly ( 36 ) to rotate. As it rotates, blowby gas is drawn through the centrifugal fan blades (60) where oil is separated from the gas and then through the turbo fan blades (52) which pushes the filtered gas into an air flow passage (28, 30) leading to the air intake system (31).
