A piston ring gasket (3) comprising two piston rings (31, 32) is arranged at a mantle surface (100). The gasket is arranged between a piston crown (4) with a top land (5) and a piston skirt (6). The piston skirt forms a lower portion that is turned away from a combustion chamber surface (7) of the piston. Centering units (8, 81) e.g. guide rings, are provided on the piston for radially centering the piston in the cylinder.",
