ABSTRACT:
A supercharger for compressing air supplied to an engine, wherein the energy of the exhaust gas is used to increase the pressure of the air admitted to the engine, has a rotor with radially extending vanes that define a plurality of rotating cells therebetween. Exhaust gas inlet and outlet ports at one axial end of the rotor and air inlet and outlet ports at the opposite end of the rotor admit engine exhaust gas and ambient air to the rotor cells and permit the flow of exhaust gas and compressed air from the rotor cells. The inlet and exhaust ports of the exhaust gas port plate are correspondingly equal in size and symmetrically disposed around the rotor circumference. The inlet and exhaust ports of the air port plate are unsymmetrically arranged around the rotor circumference and are of unequal size. A first air inlet port has an air outlet port associated with a first compression cycle; a second air inlet port has an air outlet port associated with a second compression cycle; a third air inlet port has an air outlet port associated with a third compression cycle. Each cycle operates with optimal efficiency at discrete rotor speeds.
