Abstract:
An internal combustion engine, comprising:an engine block having a plurality of cylindrical passages therein;a piston arranged to move reciprocally in a predetermined direction relative to the engine block;a drive shaft mounted in a first one of the cylindrical passages in the engine block and connected to the piston and arranged to be driven by the piston in rotational motion about a first axis perpendicular to the direction of motion of the piston;a drive pulley mounted to the drive shaft;a belt mounted to the drive pulley;a pulley shaft mounted in a second cylindrical passage in the engine block;an output pulley mounted to a first end of the pulley shaft and arranged to be driven by the belt;a first gear mounted to a second end of the pulley shaft such that the first gear and the pulley shaft have concentric axes of rotation;a second gear arranged to mesh with the first gear and be driven in rotational motion thereby such that the engine produces a rotational output about an output axis that is parallel to the direction of reciprocal motion of the piston.
