Patent ID: 11815045

Abstract:
A cylinder liner for an internal combustion engine may include a hollow-cylindrical liner body, which may have an inner circumferential surface including a first axial portion and a second axial portion. The first axial portion may open at a first opening angle towards the second axial portion. The second axial portion may open at a second opening angle away from the first axial portion. The second opening angle may be greater than the first opening angle. A first surface roughness in the first axial portion may be greater than a second surface roughness in the second axial portion. A plateau aspect in the second axial portion, which may be defined as R3p=Rvk/(Rpk+Rk), may be 0.2 to 1.6. A texture height in the second axial portion, which may be defined as R3k=Rpk+Rk+Rvk, may be 0.4 μm or less.
