Abstract
A closed crankcase ventilation system for an internal combustion engine is disclosed. The system comprises a flow path configured to enable crankcase emissions to flow from a crankcase of an internal combustion engine. A compressor is 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 is provided downstream of the compressor and configured to treat the compressed air and crankcase emissions exiting the compressor to remove entrained oil. A first conduit downstream of the treatment element is 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. A second conduit downstream of the treatment element is 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.
