Due to its special shape, a split piston ring inserted into a groove in a piston of an internal combustion engine can be set in rotation by differences in the action of gas and friction forces on it when the piston moves. This is achieved by differences in the configuration of undercuts on the upper and/or lower flank of the ring.
