Abstract

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 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.
