Abstract
A piston for an internal combustion engine may include a piston head and a piston shaft. The piston shaft may have two shaft walls, one arranged on a pressure side and the other arranged on a counter-pressure side. Two box walls may have pin bosses and connect the shaft walls. Each of the box walls may have a first partial wall section and a second partial wall section. The first partial wall section may extend between the pin boss and the shaft wall arranged on the pressure side. The second partial wall section may extend between the pin boss and the shaft wall arranged on the counter-pressure side. A first longitudinal center line of the first partial wall section is may be convergent to a second longitudinal center line of the second partial wall section, wherein the first and second longitudinal center lines—intersect each other outside the piston.
