The rotary coalescedor crankcase ventilation of an internal combustion engine and methods for separating air from oil gas in the crankcase ventilation leakage and to reduce the pressure of the crankcase of an internal combustion engine

摘要

An internal combustion engine crankcase ventilation rotating coalescer includes an annular rotating coalescing filter element, an inlet port supplying blowby gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering cleaned separated air from the exterior of the rotating element. The direction of blowby gas is inside-out, radially outwardly from the hollow interior to the exterior.
