Abstract (en)

[origin: FR2864154A1] The device (32) has a cam (42) housed between a crank pin (34) and a hole (44) provided in a connecting rod head (30). The cam has circular shape with geometric axis of the cam corresponding to its center axis, and a hole (46) with axis non coaxial with the geometric axis and merged with axis of the crank pin. The cam permits to vary compression rate of an internal combustion engine. An independent claim is also included for a method for varying compression rate of an internal combustion engine.
