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.

Internal combustion engine with ventilation system for a crankcase

A method for controlling fuel injection aspects of a fuel system of an internal combustion engine includes determining a fuel injection strategy for each engine cycle including a pilot fuel injection, a main fuel injection, and a dwell time between the pilot and main fuel injections. The method also includes automatically adjusting the dwell time for each engine cycle based on a sensed ambient temperature and ambient pressure associated with the internal combustion engine.
