Abstract
A reciprocating internal combustion engine has an engine block () with at least one pair of coaxially aligned cylinders (L andR) in which a dual-headed piston body reciprocates. Two rack gears (and) are mounted within a central frame structure () of the piston body and mesh with two pinion gears (and, respectively). The pinion gears are rotatably mounted on an axle () oriented approximately perpendicular to the line of reciprocate motion of the piston. A slip clutch (and) on each pinion gear alternatively locks and unlocks the pinion gear to the axle to permit rotation of the axle in one direction as the piston reciprocates. Preferably, fuel combustion occurs alternatively in each cylinder head. A valved chamber (L andR) in the cylinder head enables exhaust. Preferably, a flywheel () is connected to the axle.
