Abstract
In a light alloy piston for internal combustion engines, a fibrous insert body is embedded in the cast material adjacent to each of the bosses defining the piston pin bores. In order to minimize the costs of manufacturing such piston, the fibrous body extends only above the horizontal plane which includes the piston pin axis between that plane and the piston head and on both sides of the plane which includes the piston pin axis and the piston axis extends over not more than the load-carrying length of the boss defining the piston pin bore.
