Claim 0:
1. A cylinder liner for a cylinder bore of a cylinder, the cylinder liner comprising:
a cylindrical casing having an outer profile that includes an outer diameter as measured relative to a longitudinal axis of the cylindrical casing, the cylindrical casing having an inner surface that includes an inner diameter as measured relative to the longitudinal axis, wherein the inner and outer surfaces span between a top end and a bottom end of the cylindrical casing;
a liner seat on the outer profile adjacent to the bottom end of the cylindrical casing, the liner seat configured to engage a liner stop mechanism on the cylinder bore to position and support the cylindrical casing in the cylinder bore;
a relief feature on the outer profile that is positioned adjacent to and above the liner seat as measured relative to the longitudinal axis, the relief feature having a depressed profile relative to the outer profile of the cylindrical casing wherein the relief feature is configured to resist distortion of the cylindrical casing from the cylinder bore; and
a stiffening feature on the outer profile that is positioned adjacent to and above the relief feature as measured relative to the longitudinal axis, wherein the liner seat, the relief feature, and the stiffening feature are located closer to the bottom end than the top end of the cylindrical casing.
