Abstract
A cylinder bore for a cylinder housing of an internal combustion engine may have a cylinder running surface, an upper reversal point and a lower reversal point at which a piston, which may be moved up and down in the cylinder bore and may have piston rings and a piston skirt, may reach a speed which approaches zero during engine operation. The cylinder bore may also have a region between the upper reversal point and the lower reversal point at which the piston may reach a maximum speed during engine operation. The cylinder bore may further have at least two circumferential depressions formed within the region, the at least two circumferential depressions each having a diameter that may be greater than a diameter of the cylinder bore above the region and below the region.
