Claim 0:
1. An engine system comprising: a crankcase having a blow- by gas passing therethrough; a compressor configured to receive air and compress the air; an aftercooler in fluid communication with the compressor and configured to cool at least a portion of the air compressed by the compressor; an oil separating apparatus in fluid communication with the blow-by gas and configured to separate oil from the blow- by gas, wherein separate from the blow-by gas, the oil separating apparatus is in fluid communication with a boost air that includes the compressed air from the compressor; and a jet pump in fluid communication with both the blow-by gas after leaving the oil separating apparatus and the boost air after leaving the oil separating apparatus, wherein the jet pump is configured to combine the blow-by gas and the boost air; wherein the system is configured to supply boost air to the oil separating apparatus at a temperature range above a dew point temperature of the blow-by gas and below a temperature at which one or more components of the oil separating apparatus become inoperable; and wherein the boost air is in fluid communication with the oil separating apparatus and configured to pass through the oil separating apparatus in a heat exchange relationship with the blow-by gas to maintain a temperature of the blow-by gas within the oil separating apparatus at a desired temperature range.
