Abstract: The engine includes a housing having a circular cavity with a rotatable flywheel defining a radially extending power piston(s) disposed therein. An abutment disc connects to a compression piston rotor and rotates synchronously with the flywheel. Compression piston(s) rotate on separate axes within the compression piston rotor and move in and out with respect to the outer periphery of the compression piston rotor. A compression piston stator seals off the top of the compression piston rotor causing the compression pistons to compress a charge of gas to be delivered on top of the power piston(s). Fuel is injected and the combustion zone is ignited. The expanding gases force the power piston(s) and flywheel around the housing producing work. The previous products of combustion are forced out the exhaust system in front of the power piston.
