Abstract

Apparatuses, systems and methods for utilizing crankcase compression air to effect forced air induction (i.e. “boost”) into the combustion chamber of an internal combustion engine is provided. In some embodiments, the apparatuses are a supercharger apparatus that is attached to an existing engine. In other embodiments, the supercharger components are located within the structure of a novel engine itself. An embodiment of the apparatus includes a conduit that includes three inlets: 1) an inlet that is capable of being placed in fluidic communication with the crankcase chamber of an engine; 2) an inlet that is capable of being placed in fluidic communication with an intake to a combustion chamber of the engine; and 3) an inlet in fluidic communication with the atmosphere.
