Abstract
Official abstract text for this publication.
A cylinder housing for a reciprocating-piston internal combustion engine, in particular of a motor vehicle, includes a first cylinder which is delimited by a first cylinder barrel and a second cylinder which is delimited by a second cylinder barrel. The cylinders differ from one another with respect to their respective inner contour formed by the respective cylinder barrels.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cylinder housing of a reciprocating internal combustion engine, comprising: a first cylinder delimited by a first cylinder barrel; and a second cylinder delimited by a second cylinder barrel; wherein the first cylinder has a first internal contour formed by the first cylinder barrel and the second cylinder has a second internal contour formed by the second cylinder barrel; wherein the first internal contour is configured to differ from the second internal contour in a cold state of the reciprocating internal combustion engine such that a shape of the first internal contour and a shape of the second internal contour differ from each other and differ from a desired target shape in terms of a respective diameter and/or a respective honing shape of the respective cylinder barrels in the cold state of the reciprocating internal combustion engine, and such that in a fired operation of the reciprocating internal combustion engine the shape of the first internal contour and the shape of the second internal contour correspond to the desired target shape.
