Abstract:
1. A closed crankcase ventilation system for an internal combustion engine comprising: a flow path configured to enable crankcase emissions to flow from a crankcase of an internal combustion engine; a compressor configured to enhance the flow of crankcase emissions from the crankcase by drawing the crankcase emissions into the compressor, to draw air from a source, and to compress the air and crankcase emissions; a treatment element downstream of the compressor configured to treat the compressed air and crankcase emissions exiting the compressor to remove entrained oil; a first conduit downstream of the treatment element configured to introduce a first portion of the compressed air and crankcase emissions into one of an exhaust system for the engine and an air intake system for the engine; and a second conduit downstream of the treatment element configured to introduce a second portion of the air and crankcase emissions into a system having at least one component utilizing compressed air for its operation.
