An efficient and powerful engine is obtained by incorporating within an engi ne housing (2) at least one cylinder (8, 10) which is rotatable along the inner circumferential surface of the housing (2). The cylinder (8, 10) is mounted to a crank case (6). A piston rod extends from piston (54, 56) and is moveable longitudinally within the cylinder (8, 10). The piston rod (16) in turn is connected to a crankshaft (18). Thus, when the engine is powered, both the cylinder (8, 10) and the crankshaft (18) can rotate, either in the same direction or in opposite directions. An exhaust opening (32) is provided at a location substantially at the top portion of the cylinder (8, 10). A corresponding exhaust port (30) is provided in the housing (2), so that when the cylinder (8, 10) is rotated to the particular location along the housing (2), its exhaust opening (32) comes into alignment with the exhaust port (30 ) of the housing (2) so that the exhaust gases resulting from the combustion i n the cylinder (8, 10) are evacuated directly outside of the housing (2). A ge ar mechanism converts the rotational movement of either the cylinder (8, 10), t he crankshaft (18), or a combination of both, to drive the vehicle, or power generating device, to which the engine is adapted.
