ABSTRACT:
An internal combustion engine has a piston reciprocating in a cylinder within an engine block. A piston rod extending from the piston is rotatably connected to a crankshaft. The engine block has two stationary gears mounted thereon, one at each side. The crankshaft has two orbital gears mounted thereon, the orbital gears being located so that each orbital gear intermeshes with one of the stationary gears. As the piston reciprocates, the orbital gears move around the stationary gear and the crankshaft rotates about its longitudinal axis. Preferably, the size ratio of the stationary gear to the orbital gear is 2:1 respectively. With that ratio, the crankshaft rotates about its longitudinal axis three times during each stroke of the engine. The piston stops approximately midway through the downstroke and midway through the upstroke and the movement of the piston to and from top dead center is much faster than the movement of the piston with conventional engines.
