Abstract: A fuel system of a fuel injected engine includes a separate priming actuating fluid reservoir connected to an actuating fluid manifold and a high pressure pump for maintaining the volume of oil at the manifold and pump during periods when the engine is not in operation.

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.

Abstract: A supercharger for compressing air supplied to an engine having an intake manifold and an exhaust gas manifold wherein the energy of the exhaust gas is used to increase the intake manifold air pressure, the supercharger having a rotor with radially extending vanes that define a plurality of rotating cells therebetween, exhaust gas inlet and outlet ports at one end of the rotor, air inlet and outlet ports at the other axial end of the rotor, which ports open communication between the engine exhaust manifold and the engine inlet manifold respectively as the rotor rotates each cell into alignment with the ports, the rotor vanes being formed with a stiffening bead and being arranged around the rotor circumference so that they are spaced from one another by an unequal amount that may very either uniformly or nonuniformly around the rotor.

Abstract: A wave compression supercharger comprises a rotor mounted for rotation about its longitudinal axis having axially disposed cells formed about its periphery, a shroud surrounding the rotor, a first port plate located between the rotor and an air duct that delivers ambient air to the supercharger rotor and delivers pressurized air to the air intake side of the engine. A second port plate located between the rotor and an exhaust duct carries low pressure gas from the rotor and high pressure engine exhaust gas to the rotor. A hydraulic cylinder has a piston mounted for sliding motion in the cylinder. A mechanical governor driven by the rotor of the supercharger controls a source of pressurized hydraulic fluid that is opened to the cylinder according to variations in the speed of the rotor. The piston is connected to a port plate and delivers a tangential force to the plate causing it to rotate with respect to the longitudinal axis of the rotor.

Abstract: A process for making and assembling a rotary regenerator comprising a ceramic core adapted to rotate upon its central axis and a ring gear surrounding the periphery of the core for purposes of driving the core rotatably including preparing and forming a yieldable compliant ring sandwiched between the ring gear and the periphery of the core to prevent stresses in the core caused by differential rates of expansion of the core and the ring during operation of the regenerator in a gas turbine engine and during processing of the regenerator and the regenerator drive ring.
