This patent describes an internal combustion engine having a block within which at least one piston is attached to a crankshaft by a connecting rod between the crankpin of the crankshaft and the wrist pin of the piston. This patent describes improvement in a fixed gear concentric with the axis of the crankshaft and coupled to the block; a follower gear concentric with the crankpin; at least one intermediate gear coupling the fixed gear to the follower gear; wherein the ratio of the gears is such that the follower gear orbits the fixed gear and does not rotate; and linkage arms interconnecting the follower gear and the piston for preventing the rotation of the piston about the wrist pin.
