    Abstract: A cylinder liner for a cylinder bore of an internal combustion engine is provided. The cylinder liner including a hollow cylindrical body and a coolant cavity defined between a sidewall of the cylinder bore and an outer surface of the cylinder liner. A plurality of lower seal grooves are provided in the outer surface of the cylinder liner. A lower liner support is arranged between an uppermost one of the lower seal grooves and the coolant cavity. The lower liner support has an asymmetric configuration in a circumferential direction such that a clearance between the sidewall of the cylinder bore and the outer surface of the cylindrical body is relatively less in an area surrounding a thrust/anti-thrust plane and is relatively more in an area surrounding a perpendicular plane.

    Abstract: A cylinder liner assembly for inclusion in the cylinder bore of an internal combustion engine includes a sleeve-like cylinder liner and an anti-polishing ring to scrape combustion deposits from a piston reciprocally movable along an axis line of the cylinder liner. A fire dam may axially protrude from a first liner end of the cylinder liner and may have an obliquely angled chamfer disposed therein circumscribing the axis line. To locate the anti-polishing ring proximate to the top land of the piston when at the top dead center position, the anti-polishing ring can include a cuff header disposed at the first cuff end that is generally triangular and has an angled undercut corresponding to the obliquely angled chamfer. When mated, the chamfer and angled undercut abut against each other.
