Title: PISTON OF AN INTERNAL COMBUSTION ENGINE HAVING ALKALI METAL COOLING AND METHOD FOR PRODUCTION THEREOF
Abstract:
The invention relates to a method for producing a piston (1) of an internal combustion engine, wherein in the piston (1) at least one cavity (2) is created which is filled with a cooling medium, in particular an alkali metal, and is subsequently closed. The at least one cavity (2) for receiving the cooling medium is designed as a longitudinally extending cavity (2) and, starting from a central hole (10) is introduced in the direction of the piston circumference into the piston body of the piston (1). The invention further relates to a piston (1) produced according to this method.
