ABSTRACT:
A reciprocating internal combustion engine includes a dual-headed piston body formed by two piston heads mounted at opposite ends of a central yoke structure. The piston heads are adapted to reciprocate within respective opposed cylinders of a coaxially aligned cylinder pair. An internally toothed roller gear is mounted for rectilinear movement within the yoke structure. The roller gear is engageable with a crankshaft drive gear and control and actuator means are provided for effecting sychronized movement of the roller gear within the yoke structure to maintain constant engagement of the roller gear with the crankshaft drive gear as the pistons of the dual-headed piston body reciprocate within respective cylinders of the cylinder pair. The central yoke structure of the dual-headed piston body is adapted to receive roller gears of different size, thus allowing the piston stroke and cylindrical volume of the engine to be varied.
