Abstract

A piston for an internal combustion engine comprising a piston head provided with at least one piston ring groove and a piston body having a piston pin bore, and a compression height of less than 40% of the piston diameter. In order to be able to equalize the influences of thermal expansion as well as possible and to enable a quiet operation of the piston in a cylinder, the invention provides that the largest diameter region of the piston body is arranged in a plane which extends perpendicularly to the body-generating line and which includes the piston pin axis.
