Piston () of an internal combustion engine, which piston is designed in structured construction, comprising two oppositely arranged load-bearing skirt wall portions (), wherein a connecting wall () respectively extends, starting from a pin boss (), in the direction of the side edge of the load-bearing skirt wall portions (), characterized in that in an interior of the piston () is (are) disposed at least one rib (), preferably three ribs (), and the material of the regions around the at least one rib () is reduced.

Piston with a structured design

A piston of an internal combustion engine has a piston crown with annular grooves and a shaft part disposed on the piston crown. The shaft part has bearing shaft wall sections which are connected to one another via inclined connecting walls which are retracted with respect to the outer diameter of the piston. Piston-pin bosses for accommodating a piston pin are disposed in connecting walls. The connecting walls are retracted at such an angle that, in progressing from the lower edge over an intermediate region which lies further back than the lower edge, into an end region which lies further back than the intermediate region the connecting walls to over flush into a hub supporting region below the piston crown.
