Abstract
Apparatuses, systems and methods are disclosed including an internal combustion engine. The internal combustion engine can include an engine block defining a combustion chamber and a crankcase in fluid communication with the combustion chamber. The internal combustion engine can include an auxiliary device in fluid communication with the crankcase of the engine block. The auxiliary device is driven by the internal combustion engine to supply air to the crankcase of the engine block at a desired pressure range and a desired mass flow rate range to ventilate the crankcase.
