A rotary engine utilizing hydrocarbon fuel having a circular rotor with one or more spaced pistons which are in sealing relationship with a generally circular torus. One or more compression expansion valves which rotate about an axis tangent to the torus wall are in sealing relation with the rotor and have a combustion chamber formed in the hub thereof. As the valve rotates about an axis, compression and expansion ports alternately communicate with the interior of the torus. One or more divider valves separate the intake and exhaust functions of the cycles and have a rotation about an axis tangent to the torus wall. The divider valves are in sealing relationship with the rotor body with a notch which allows the pistons to pass therethrough. The piston draws a vacuum on the intake valve, pulling gas into the torus and compressing the gas ahead of the piston into the combustion chamber through a compression port. As the rotor rotates, the combustion chamber rotates simultaneously the gas is ignited, and expands against the trailing face of the piston as the expansion ports of the combustion chamber align with the working area of the torus. The gases push the piston away from the compression-expansion valve rotating the rotor, and the piston simultaneously pushes previously exhausted gas out the exhaust ports.
