Abstract
A piston for an internal combustion engine is provided. The piston has a surface on the combustion side, wherein a depression having a depression edge and a depression floor is arranged in the surface and the depression has a maximum depth of tmax in an axial direction of the piston, measured from the combustion side surface. The combustion side surface furthermore has at least one protrusion that is arranged on a section of the depression edge and has a depth taus, wherein the depth taus of the protrusion is smaller than the depth of the depression tmax in the axial direction of the piston.
