摘要:A piston for an internal combustion engine has a piston head with a circumferential ring belt and a circumferential cooling channel in the region of the ring belt, and a piston skirt having a working surface assigned to each of its major thrust side (DS) and its minor thrust side (GDS). At least one bore that proceeds from the cooling channel is provided. The bore ends in the working surface assigned to the minor thrust side (GDS), in the form of a bore opening, and is disposed at an incline, in such a manner that it encloses an acute angle (α) with the center axis (M) of the piston. The working surface assigned to the minor thrust side has a depression in the region of the bore opening.
