| 20080245335 | Piston for an internal combustion engine - A piston for an internal combustion engine, comprising a piston head having a piston crown, a circumferential top land, and a circumferential ring belt having ring grooves. At least one ring groove is provided with a ring insert. A circumferential depression is provided in the top land, above the ring belt. | 10-09-2008 |
| 20080264376 | Piston for an internal combustion engine - 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. | 10-30-2008 |
