The cylinder head of each power cylinder of this internal combustion engine includes an auxiliary cylinder in communication with the power cylinder. An auxiliary piston is moveable within the auxiliary cylinder in synchronism with the power piston. During the compression stroke of the engine the auxiliary piston is retracted and the auxiliary cylinder becomes filled with the combustible mixture. This mixture is transferred back to the power cylinder as the power piston moves away from its upper dead center position. Thus the time during which the mixture is at maximum compression is increased and therefore the explosion takes place when the crank shaft has already rotated through an appreciable angle from the upper dead center position. Thus the torque exerted by the power piston is considerably increased with respect to the conventional engine. To further increase this torque the axis of the crank shaft is laterally offset from the center line of the power cylinder in a direction to increase said torque.
