  • Patent number: 11415076
    Abstract: A method for producing a piston blank or a piston for an internal combustion engine, includes providing a thickened portion formed in at least one box wall in the direction of thickness approximately in the center thereof, which is at least partly flush with a cooling channel. A resulting piston blank or piston having these features can be made in a casting mold or forging die designed in a corresponding manner.

  • Patent number: 11193448
    Abstract: A piston for an internal combustion engine has box walls (18), which are each formed between skirt walls (12) and gudgeon pin bosses (10). At least one of the box walls (18) on a thrust side at least on the lower edge and at least on the inner side, starting from the gudgeon pin boss (10), in a first portion (20), runs largely straight and is inclined outwards, and then runs curved inwards, and then, in a second portion (16), runs largely straight and inclined inwards to the skirt wall (12).

  • Patent number: 11131269
    Abstract: A steel piston (10) for an internal combustion engine has a cooling channel and shaft surfaces (12, 14) with which the piston (10), in the installed state, abuts a cylinder bore or a cylinder liner on a pressure side and a counterpressure side, wherein one shaft surface (12) has a width which is 25-50% smaller than the other shaft surface (14).
