Verfahren zur Herstellung eines Kolbens einer Brennkraftmaschine und nach diesem Verfahren hergestellter Kolben

摘要

A piston for an internal combustion engine includes an insert defining an air chamber opening into the combustion chamber. The insert is preformed to a desired configuration and the piston cast around the insert thus providing a means of securing the insert within the structure of the piston. The insert may be located wholly within the piston or may have a flange part which extends over an outer surface of the piston.
