An apparatus for supercharging a four cycle internal combustion engine has at least one inlet reed or check valve and at least one outlet reed or check valve associated with each cylinder of the internal combustion engine. The crankcase of the engine is maintained air tight and if the engine is multi-cylindered, the crankcase must be provided with some form of air tight separation between each cylinder inside the crankcase. When the engine is rotating, each up-stroke of each piston causes an air charge to enter the respective crankcase section for that cylinder through its associated inlet reed or check valve. Each down-stroke of the piston causes compression of the charge in the associated section of the crankshaft and delivery of this pressurized charge through the associated outlet reed or check valve. The outlet reed or check valve is in communication with the carburetor or fuel injection system of the engine to provide this supercharged charge to the intake system of the internal combustion engine thus supercharging the engine.
A pulse charger for an internal combustion engine, said engine having an air intake and a crankcase, said crankcase defining an internal cavity, said pulse charger comprising:
A pulse charging system for a four cycle internal combustion engine, said engine having a crankcase, a plurality of pistons, and an air intake, said crankcase defining a plurality of cavities, each of said plurality of cavities being associated with a respective piston of said plurality of pistons, said pulse charging system comprising:
