Abstract
Apparatuses, systems and methods are disclosed for separating oil from a blow-by gas of an engine. An example includes engine system includes a crankcase having a blow-by gas passing therethrough, a compressor configured to receive air and compress the air, an aftercooler, an oil separating apparatus and a jet pump. The aftercooler communicates with the compressor and is configured to cool at least a portion of the air compressed by the compressor. The oil separating apparatus communicates with the blow-by gas. The oil separating apparatus communicates with a boost air that is a mixture of the compressed air from the compressor and cooled air from the aftercooler. The jet pump communicates with both the blow-by gas after leaving the oil separating apparatus and the boost air after leaving the oil separating apparatus and is configured to combine the blow-by gas and the boost air.
