ABSTRACT:
A rotary internal combustion engine with four vanes carried by a rotor engaging an internal oval housing surface to define four chambers that orbit the rotor axis. Two of the chambers, diametrically opposed, are operated as working chambers on a four-phase internal combustion engine basis in phase with each other. Supercharging is continued through an early part of the volume expansion and firing phase, whereby the rate of expansion per degree of rotation is substantial at the time firing is initiated. The other two chambers are operated as air pumping chambers to supercharge the working chambers via an air pressure accumulator. A lubricating liquid within the chamber is introduced into the pumping chambers for engine lubrication with excess being returned to the accumulator. The pressure of the liquid is applied hydraulically against the vanes to urge each radially outward with equal force. Excess air in the accumulator is vented to commingle with hot exhaust to further oxidation thereof and to limit accumulator pressure.
