METHOD FOR THE PRODUCTION OF A PISTON OF AN INTERNAL COMBUSTION ENGINE IN ORDER TO FORM A REINFORCEMENT OF A COMBUSTION CHAMBER CAVITY OF THE PISTON

摘要

A method for producing a piston of an internal combustion engine in which a first blank and at least one additional black are provided with a somewhat cylindrical shape. The blanks are joined together, and the obtained piston blank is subjected to a shaping process in which a combustion chamber cavity of the piston is formed in the area of a joining point between the first and the second blank. The material of the second blank forms a reinforcement for at least the combustion chamber cavity.
