  • Patent number: 8752521
    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.

  • Publication number: 20110174153
    Abstract: The invention proposes a piston (10) for an internal combustion engine, having a piston crown (11), having a fire land (12), having an encircling ring section (13) which has annular grooves (14), and having a piston shank (15) which has two shank walls (16, 17) arranged on the pressure side (DS) and on the counterpressure side (GDS) and two box walls (18, 19) which connect the shank walls (16, 17) to one another, wherein the box walls (18, 19) are provided with pin hubs (21) which have hub bores (22), and wherein the shank wall (16) arranged on the pressure side (DS) is shorter, as viewed in the circumferential direction of the piston (10), than the shank wall (17) arranged on the counterpressure side (GDS). To reduce the loading of the piston, the pressure-side box walls (18) run rectilinearly and obliquely, wherein the spacing of the box walls (18) is greater in the region of the pin hubs (21) than in the region of the pressure-side shank wall (16).

  • Publication number: 20080264376
    Abstract: 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.
