  • Closed crankcase ventilation system
    Patent number: 7434571
    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.

  • Closed crankcase ventilation system
    Patent number: 7320316
    Abstract: A closed crankcase ventilation system for an internal combustion engine is disclosed. A compressor is configured to compress air and enhance the venting of crankcase emissions from a crankcase of the engine. A flow path is provided between the crankcase and an intake of the compressor. A prioritizing device is situated in the flow path and configured to regulate the flow of crankcase emissions and control pressure within the crankcase. A treatment element is provided downstream of the compressor and configured to treat the compressed air and crankcase emissions 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.
