A double-acting, single-cylinder, internal combustion engine that is provided with auxiliary components which optimize the intake stroke is disclosed. The auxiliary components are arranged in such a way that the intake of the fuel gas mixture to be burnt is not controlled by the piston. In general the engine includes a cylinder in which a piston reciprocates. A shaft is affixed to each side of the piston and is coaxial therewith. The shafts include auxiliary pistons which reciprocate in inlet chambers. Each shaft includes a portion of reduced diameter or ports adjacent the piston through which the fuel gas mixture is injected into the respective combustion chamber through cylinder heads located at opposite ends of the cylinder. The cylinder is further provided with exhaust ports at the center of its sidewall. A connecting rod is rotatably connected to at least one of the shafts, and the engine performs two combustion cycles during each revolution of the connecting rod.
