Abstract: A piston for an internal combustion engine may include a piston skirt extending in a piston longitudinal direction and defined in the piston longitudinal direction by a piston head. The piston skirt may include a boxed interior space defined by two box walls and two substantially opposing skirt walls. A boss having a through-opening may be arranged on each of the two box walls, the two through-openings being oriented so that they align with one another. The two box walls may each include a boss portion oriented perpendicularly to the boss, and at least one intermediate portion extending between the respective boss portion and one of the skirt walls. The intermediate portion may merge via a bend into the associated boss portion. A radial extent of the boss portion may be greater than a diameter of the through-opening and at least 50% of a diameter of the piston.

Abstract: A piston for an internal combustion engine may include a surface in a region on a crankshaft side. The piston may include a thermally conductive coating disposed on the surface via thermal spraying.

Abstract: A piston for an internal combustion engine may include a plurality of pin bores for accommodating a piston pin. The pin bores may be transversely oval to a longitudinal axis of the piston. The pin bores may be formed in a circular cylindrical manner at a zenith of ?=0° and at a nadir of ?=180°. The pin bores may be formed in an oval manner with an oil-holding volume at an equator of ?=90° and ?=270°. The pin bores may include a transition between the equator and the zenith and between the equator and the nadir that runs in a continuous and differentiable manner.
