Abstract: Disclosed is a short stroke, rapid fire, continuous power rotary engine which can be affixed to the body of a vehicle or other stationary position, depending upon its intended use. The engine includes a housing within which is a rotating block which houses the pistons and at least one cylinder. A central power shaft having first and second sections mounted within the housing is connected to the rotating block. Upon ignition, the expanding gases urge the pistons radially outwardly from the axis of the central power shaft. Further provided are piston rods and means for transmitting the radially outward movement of the pistons to the rotating block, thereby imparting a rotational moment thereto. The engine also includes a fuel intake system and novel ignition and exhaust systems.
