ABSTRACT:
A multiple piece piston is provided for a diesel internal combustion engine having a combustion chamber depression in the crown of the piston. In order to achieve a low rate of heat flow into the piston ring area and thus into the cylinder liner which surrounds the piston, a separate piston base or crown surrounding the combustion chamber depression is formed by a ring element made of a material having poor thermal conductivity, and the main body of the piston is made of a material with high thermal conductivity. The heat of combustion is thus conducted mainly axially through the piston main body and absorbed by sprayed cooling oil. The cooling oil, thus heated, can be utilized for heating purposes.
