ABSTRACT:
A reciprocating piston internal combustion engine has a scotch yoke-type motion translator. The engine is horizontally opposed with each shuttle having a pair of pistons attached at the ends of a pair of oppositely extending arms. A centrally located aperture in the shuttle accommodates the crankpin and incorporates a pair of rack blocks bolted to the shuttle. The rack blocks mesh with mating epicycloidal/hypocycloidal sectors rotatably mounted upon a crankpin and forming the interface between crankshaft and shuttle. The cycle dynamics of the engine may be matched to the thermodynamics of a selected power cycle and fuel by adjusting the shape of the sectors and racks.
