Abstract
Official abstract text for this publication.
A piston for an internal combustion engine includes a piston head and a piston skirt, wherein the piston head has a piston base, a circumferential ring part and, in the region of the ring part, a circumferential closed cooling channel or sealed cavity. An inner side of the piston has two lower surfaces which transform continuously in the region of the piston central axis (M) to form an arched surface. The piston skirt has piston hubs provided with hub bores which are interconnected by means of running surfaces which have inner surfaces facing the inside of the piston. Starting from the free ends of the piston skirt, inside the piston on the pressure side (DS) and/or counter pressure side (GDS), an inner surface of a running surface continuously transforms into a guiding surface for a coolant which transforms continuously on the side thereof into a lower surface.
First claim
Opening claim text (preview).
The invention claimed is: 1. Piston for an internal combustion engine, having a piston head and a piston skirt, wherein the piston head has a piston crown, a circumferential ring belt, as well as a circumferential, closed cooling channel or closed cavity in the region of the ring belt, wherein an inside of the piston has two lower surfaces that make a constant transition into an arched surface in the region of a center piston axis, wherein the piston skirt has pin bosses provided w…
