Kolben für einen Verbrennungsmotor und Verfahren zur Herstellung eines Kolbens

摘要

The main body of the piston (12) is cast in aluminum or aluminum alloy. From the base of the piston up to the region between the gudgeon pin bores, this has a penetrating recess. A largely conical reinforcing insert (16) of highly heat-resistant material, is joined to the main body, preferably by welding. An Independent claim is included for the corresponding method making a piston.
