ABSTRACT:
An improved engine output shaft includes a crankpin assembly for operatively connecting the shaft to each reciprocating piston for translating the reciprocating motion of each piston to rotary motion of the shaft through a leverage arm between the axis of rotation of the shaft and the point of operative connection between each piston and the shaft. The crankpin assembly is fixed to rotate with the shaft and defines a plurality of fixed crankpin offsets and transition offsets which sequentially vary the moment arm in a predetermined manner during the rotation of the shaft to produce a substantially constant total engine torque output during each increment of rotational movement. A transition guide system is provided to create a smooth, controlled movement of a connecting rod between the fixed crankpin offsets. The transition guide system includes a plurality of rollers mounted on a transverse support connected to the crankpin and a guide cam surface formed on the connecting rod for guiding contact by the rollers. A crankpin offset maintaining system, including a roller mounted on a second transverse support and an abutment surface formed on the connecting rod, maintains the crankpin offsets during rotation between the transition periods.
