摘要:
A piston (10) for an internal combustion engine includes a groove (16) for an oil wiper ring and a recess (18) between the groove (16) and at least one shaft wall (20). A lower edge of the groove (16), which is closer to the shaft wall (20), has a larger diameter than a lower edge of the recess (18).
