A rotor chamber and cooperating lubricant passages are defined within an engine housing having a plurality of heat-transfer fins on the exterior surface thereof. A rotor having fluid passages therein is rotatably disposed within the chamber on a shaft, and a pair of lever wheels is rotatably supported within recessed chambers provided in the rotor. Rotatable combustion chambers are defined between adjacent lever arms, and the end of each lever arm engages arm-receiving recesses disposed about the rotor chamber periphery. Cooling and exhaust fans are coaxially supported on the rotor shaft to draw cooling air over the engine casing and to extract exhaust gases from the engine, respectively. The tip and sides of each lever arm are provided with pivotal sealing elements biased into contact with the surfaces of the recessed chambers to provide sealing forces proportional to the pressure of the combustion gases.
