Patent ID: 8616188

Claim:
An engine air management system for an internal combustion engine generating blowby gas in a crankcase containing engine oil and oil aerosol, said system comprising a combined crankcase ventilation filter and air cleaner comprising an air-oil separator having an inlet receiving blowby gas and oil aerosol from said crankcase, and having an air outlet discharging clean blowby gas, and an oil outlet discharging scavenged separated oil said system further comprising a combustion air intake supplying combustion air to said engine, said combustion air intake including an air filter supplying clean combustion air to said engine, and comprising a housing having first, second and third ports, said first and second ports being inlet ports, said third port being an outlet port, said housing having first and second chambers, said first chamber containing an air filter, wherein combustion air flows from upstream to downstream through said first port then through said air filter in said first chamber then through said third port to said engine, said second chamber containing said air-oil separator, wherein said blowby gas and oil aerosol flow through said second port to said air-oil separator in said second chamber, wherein said housing extends axially along an axis, and said first and second chambers extend axially and are laterally aligned in side-by-side relation, wherein said housing has an axially extending dividing wall laterally between and separating and isolating said first and second chambers.
