| description | The invention relates to a piston (1) of an internal combustion engine, which piston (1) has a piston head (2) with a ring field (3) and a skirt part which is arranged on the piston head (2), wherein the skirt part has at least two load-bearing skirt-wall sections (4a, 4b), and the load-bearing skirt-wall sections (4a, 4b) are connected to one another via at least two obliquely positioned box walls (5) which are set back with respect to the piston external diameter. In each case one pin boss (9) for receiving a piston pin is arranged in the box wall (5) and one skirt-wall section (4a) forms the pressure side and the other skirt-wall section (4b) forms the counter-pressure side. According to the invention that the inner surface of the pin boss (9), in relation to the piston centre, runs flushly with respect to the surface of the associated box wall (5), and the box wall (5) has a concave profile in the transverse extent with respect to the direction of the pin boss (9). Furthermore, the invention relates to a connecting rod of an internal combustion engine. |
