Abstract
A compressor assembly includes a compressor housing having an inlet port configured to receive intake air and an outlet port configured to discharge pressurized air. A hollow section having an inner radial surface defines the inlet port of the compressor housing. A compressor wheel is disposed in the hollow section. A positive crankcase ventilation (PCV) passage is configured to allow airflow between a crankcase of an engine and the hollow section of the compressor housing. The PCV passage has an outlet opening that opens into the hollow section of the compressor housing and the inner radial surface includes an integrally formed raised boss surrounding the outlet opening and protruding into the hollow section.
