Abstract: The engine has two contrarotating rotors (2) in an engine housing (1), each lying on a central axis. The working rotor has a protrusion that slides on the housing wall in gas-tight manner and the auxiliary rotor has a depression. Inlet and outlet valves (5) are driven via camshafts. And the working and auxiliary rotors are driven via gearwheels. The housing is water-cooled and variable compression can be achieved by varying the induction and combustion (4) chamber volumes.
