Abstract
Apparatuses, systems and methods are disclosed including internal combustion engine optionally including: a crankcase having a blow-by gas passing therethrough; a source of a boost air; a jacket containing a water; an oil separating apparatus in fluid communication with the boost air and the blow-by gas and having a coalescing filter to separate oil from the blow-by gas; and a heat exchanger in fluid communication with the boost air, wherein the heat exchanger is in fluid communication with the jacket to receive the water, wherein the water is passed in a heat transfer relationship with the boost air in the heat exchanger to achieve a desired temperature range for the boost air passing to the oil separating apparatus.
