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.
