Abstract
Die Erfindung betrifft einen Kolben (1) für eine Brennkraftmaschine, umfassend einen Kolbenboden (2), in dem eine Brennraummulde (3) integriert ist, die einen Muldenboden (4) umfasst, der über einen Muldenrand (5) mit zugehörigem Muldenrandradius (6) mit dem Kolbenboden (2) verbunden ist. Die Brennraummulde (3) schließt zumindest einen beliebig geometrisch gestalteten Muldenboden (4) ein, der gegenüber dem Muldenrand (5) und/oder dem Muldenrandradius (6) eine übereinstimmende oder abweichende geometrische Form aufweist.
