Abstract

The invention relates to a heated inlet of a crankcase ventilation system. 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 aninlet of the crankcase to purge blow-by gases including natural gas from the crankcase.

Description

technical field [0001] The present disclosure relates generally to crankcases for internal combustion engines, and more particularly to heated inlets for crankcase ventilation systems for such internal combustion engines. Background technique [0002] Internal combustion engines typically include a crankcase to provide a housing for the engine's crankshaft. During operation of the engine, blow-by gases (eg, gaseous fuel, air, and / or combustion gases) may leak into the crankcase. Blow-by gases can contaminate an engine's oil lubrication system, can pressurize the crankcase, and can affect overall engine emissions. Additionally, if the engine is fueled with a gaseous fuel (eg, natural gas or landfill gas), the blow-by gas may include corrosive fumes such as sulfur. The crankcase may include a ventilation system, such as an inlet / outlet breather system, to assist in purging blow-by gases from the crankcase with fresh ambient air. When the engine is used in a cold environment...
