PISTON FOR AN INTERNAL COMBUSTION ENGINE AND METHOD FOR PRODUCING SAME

摘要

A piston for an internal combustion engine has a piston head having a piston crown, and a piston skirt, a first part of the piston head being formed by a piston base, and a second part of the piston head being formed by a piston head element, and a peripheral cooling channel being provided in the piston head. At least one heat-conducting element is arranged in the cooling channel and is connected to the piston base and the piston head element via an external seam and an internal seam which extend from the piston crown to the cooling channel. The invention further relates to a method for producing the piston.
