Abstract

A light metal piston arrangement, for an internal combustion engine or for a compressor, which has a crown, skirt, and shoulder for the bolt, and an insert made of a material with a lower coefficient of expansion than that of light metal and shaped so that at least part of the insert conforms to the internal shape of the piston skirt, whereby a bimetal element is formed with the light metal of the piston to perform deformation of the skirt shape when heated the piston, the insert being formed as two bands that extend at least in part of the internal contour of the piston from the region of the protrusions for the bolt, one band being spaced parallel to the other and closer to the crown of the piston that the latter, the bands being connected by a connecting part of the insert in the region of the adjacent shoulder for the bolt.
