Abstract
A crank-connecting rod mechanism for an internal combustion engine or the like comprising a shaft rotating around its axis, a first crank fixed to the shaft and a crank pin fixed to the first crank. A crank pin extends parallel to but at a first radial distance from the shaft. A second crank rotatably mounted onto the first crank pin is fixed to a second crank pin having an axis at a second radial distance from the axis of the first crank pin. A connecting rod is rotatably mounted on the second crank pin. Rotary means are provided to force the second crank to rotate relative to the first crank upon a rotation of the shaft.
