ABSTRACT:
Variable displacement reciprocating piston engine arrangements are disclosed wherein pistons drive a variable displacement oscillating rocker member connected with an oscillating lever that in turn drives a rotating shaft through a crank mechanism. The rocker member and oscillating lever are engaged at a sliding joint displaced from their spaced axes, forming an angular multiplier drive. The rocker member and its axis are movable to vary the piston stroke by changing the lever arm of the oscillating shaft connection with the rocker member, while at the same time the piston compression ratio is held constant or varied in a predetermined manner through adjustment of the piston positions by the same movement of the rocker member. Various drive and balancing arrangements are disclosed.
