Abstract
A method for ventilating a crankcase of an internal combustion engine using natural gas as a fuel source may include filtering ambient air through an air filter. The method may also include heating the filtered ambient air by a jacket heat exchanger. The method may further include directing the heated ambient air through an inlet of the crankcase to purge blow-by gases including natural gas from the crankcase.
