An internal combustion engine is described comprising: an engine block defining a cylinder, a cylinder head closing one end of the cylinder, a power piston in the cylinder, a crank shaft journalled in the engine block at the other end of the cylinder, and a connecting rod pivotally connecting the power piston and the crank shaft. The power piston is reciprocable in the cylinder between upper and lower dead center position. The cylinder space between the power piston and the cylinder head defining a working chamber for receiving a combustible mixture to be ignited by ignition means, intake and exhaust valves in the cylinder head, the axis of the crank shaft is laterally offset from the longitudinal axis of the cylinder, so that the connecting rod longitudinal axis makes an angle with the cylinder longitudinal axis when the connecting axis intersects the crank shaft axis. The angle is in a direction to increase a resulting torque arm between the power piston and the crank shaft axis during each power stroke of the power piston, and the connecting rod longitudinal axis substantially coincides with the longitudinal axis of the cylinder when ignition of the combustible mixture occurs.
