  • Particular arrangement of a cooling duct connecting bore of a cooling duct
    Patent number: 10221807
    Abstract: The arrangement relates to a method for producing a cooling duct piston for an internal combustion engine, having the steps of producing a top piston part by introducing a combustion bowl, a cooling space of a part of a cooling duct and overflow ducts, producing a bottom piston part by introducing a part of a cooling duct, and joining the piston parts, wherein at least one transfer duct is created by bores. A cooling duct piston produced by the method is disclosed.

  • Piston for internal combustion engines, produced by means of a multi-orbital friction welding method
    Patent number: 8789273
    Abstract: A method for producing a piston of an internal combustion engine, designed as a one-piece cooling channel piston. The piston includes an upper part and a lower part supported by corresponding circumferential joining bosses together forming a joining zone. In order to produce a bonded joint of the upper part and the lower part, the joining bosses are connected by means of multiorbital friction welding in the region of a rotationally symmetrical or rotationally asymmetrical joining zone.

  • 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
    Publication number: 20100037765
    Abstract: 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.
