Abstract
A system includes at least one coalescer, a blow-by input module, and a boost air module. The at least one coalescer is configured to receive a blow-by mixture, to remove oil from the blow-by mixture to provide an oil drain supply, and to remove gas from the blow-by mixture to provide a gas vent supply. The coalescer is configured to receive an operational air supply. The blow-by input module is operably coupled to the at least one coalescer and configured to receive the blow-by mixture from a crankcase of an internal combustion engine and provide the blow-by mixture to the at least one coalescer. The boost air module is operably coupled to the at least one coalescer and configured to receive an air supply from an intake conduit of the internal combustion engine and to provide the air supply as the operational air supply to the at least one coalescer.
