Abstract

Improvements introduced in a piston for an internal combustión engine comprising a skirt portion; a crown portion that exceeds the skirt portion; a cavity formed in said crown portion; a thin-walled shell of heat-resistant metal placed in said cavity and covering a part of the surface thereof, the arrangement being that the surface of the shell and any surface of the cavity left exposed thereby constitute a combustión chamber .
