摘要： 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 centre line of the first partial wall section is may be convergent to a second longitudinal centre line of the second partial wall section, wherein the first and second longitudinal centre lines—intersect each other outside the piston.

摘要： The invention relates to pin bosses (1) of a piston (2) for an internal combustion engine, each comprising a pin bore (3) for supporting a piston pin (14). In order to reduce the tangential stresses in the zenith area of the pin bores and thus to extend the service life of the piston, the inner areas (16) of the pin bores (3) as viewed in the direction of the bore axis (13) have areas on both sides of the zenith (4) that have a greater distance from the bore axis (13) than the zenith (4) of the pin bore (3), and the outer areas (17) of the pin bores (3) as viewed in the direction of the bore axis (13) are transversely oval relative to the piston axis (7).

摘要： A piston for an internal combustion engine has a piston crown, a circumferential top land, and a circumferential ring belt having ring grooves, as well as having a piston skirt that has two skirt walls disposed on the major thrust side and the minor thrust side of the piston, and two box walls, set back with regard to the ring belt, that connect the skirt walls. The box walls have pin bosses with pin bores. The skirt wall disposed on the major thrust side is shorter, in a circumference direction of the piston, than the skirt wall disposed on the minor thrust side.
