Abstract
A cylinder liner for an internal combustion engine may have a running surface, in which by honing directed honing grooves may be introduced. The running surface may have a first region and a second region, wherein the first region may have a roughness that may be distinct from a roughness of the second region. A transition between the first region and the second region may proceed obliquely to a cylinder longitudinal axis at least in some portions. At least some of the honing grooves at the transition between the first region and the second region are uninterrupted.
