1. A cylinder liner for an internal combustion engine, comprising:
a hollow-cylindrical liner body extending along an axial direction, the liner body having an inner circumferential surface including, along the axial direction, a first axial portion and a second axial portion;
the first axial portion formed one of cylindrically and conically, and opening at a first opening angle towards the second axial portion;
the second axial portion opening at a second opening angle away from the first axial portion;
wherein the second opening angle is greater than the first opening angle;
wherein a first surface roughness of the inner circumferential surface in the first axial portion is greater than a second surface roughness in the second axial portion;
wherein a plateau aspect of the inner circumferential surface in the second axial portion, which is defined as R3p=Rvk/(Rpk+Rk), is 0.2 to 1.6; and
wherein a texture height of the inner circumferential surface in the second axial portion, which is defined as R3k=Rpk+Rk+Rvk, is 0.4 μm or less.
