ABSTRACT:
A piston for internal combustion engines, especially Diesel engines, with a combustion chamber arranged in the piston head which latter is preferably designed as a ring carrier and is supported by a mantle connecting the ring carrier with the foot portion of the piston. The mantle partially surrounds the combustion chamber, and thermal insulation material or the like is provided between the mantle and the combustion chamber at least within the region of the combustion chamber opening. In addition to the just mentioned thermal insulation material, there are additional thermal insulation provisions made on the mantle between the latter and the ring carrier and/or the foot portion of the piston. The piston and the cylinder therefor are so designed with regard to each other that the piston engages the cylinder over a section located between the plane of the combustion chamber opening and an adjacent piston ring carried by the ring carrier.
