Abstract
Piston for an internal combustion engine, preferably a gas engine comprising a pre-chamber, comprising a piston crown limiting the piston on a side facing a cylinder head when the piston is arranged inside an internal combustion engine, wherein the piston crown comprises at least one piston bowl which has a lower surface level than a radial edge region of the piston crown, wherein the piston bowl comprises a depth (d), which is defined by the distance between the radial edge region and the lower surface level of the piston bowl measured parallel to central elevation which has a height (H), wherein the height (H) of the central elevation equals the depth (d) of the piston bowl plus/minus 50%, preferably 20%, of the depth (d) of the piston bowl.
