Profiled cylinder liner for bore distortion control

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 surface, wherein the outer profile includes an outer diameter as measured relative to a longitudinal axis of the cylindrical casing, the cylindrical casing includes an inner surface, the cylindrical casing configured to assemble with the cylinder bore, wherein the inner and outer surfaces span between a top end and a bottom end of the cylindrical casing;
• a stiffening feature on the outer surface of the cylindrical casing, wherein the stiffening feature includes a raised profile relative to the outer diameter of the outer profile of the cylindrical casing;
• a relief feature positioned adjacent the stiffening feature on the outer surface of the cylindrical casing, the relief feature and the stiffening feature configured to resist radial distortion of the cylindrical casing from the cylinder bore;
• and
• a liner seat positioned adjacent the relief feature on the outer surface 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, wherein the stiffening feature, the relief feature, and the liner seat are located closer to the bottom end than the top end of the cylindrical casing.
