Claims

[Claims for Utility Model Registration] (1) An internal combustion engine characterized by being equipped with an unbalanced force generating mechanism that unbalances the tension acting outward in the radial direction of the piston ring in the circumferential direction of the piston ring. piston ring. (2) In the internal combustion engine according to claim 1, the unbalanced force generating mechanism is configured to have different thicknesses at approximately 90° in the circumferential direction around the abutment of the piston ring. piston ring. (3) The piston ring for an internal combustion engine according to claim 1, wherein the unbalanced force generating mechanism is constructed by having different radii at both end portions facing the abutment of the piston ring in a free state. (4) The piston ring for an internal combustion engine according to claim 1, wherein the unbalanced force generating mechanism is a notch formed in a part of the inner surface of the piston ring. (5) The piston ring for an internal combustion engine according to claim 1, wherein the unbalanced force generating mechanism is configured by performing different heat treatments in the circumferential direction of the piston ring. (6) The piston ring for an internal combustion engine according to claim 1, wherein the unbalanced force generating mechanism is a substantially wave-shaped annular plate spring interposed between the inner surface of the piston ring and the ring groove of the piston.
