    Abstract: A cylinder liner for a cylinder bore of a cylinder of an internal combustion engine. The cylinder liner includes a cylindrical casing having an outer surface and an inner surface, wherein each surface has a respective surface area. The liner includes a liner seat positioned on the outer surface wherein the liner seat engages with the cylinder bore to position the cylindrical casing in the cylinder bore. The liner includes a relief feature positioned on the outer surface either adjacent the liner seat or above a mid-stop wherein the relief feature resists distortion of the cylindrical casing from the cylinder bore. The liner can include a stiffening feature positioned above the relief feature on the outer surface. The relief feature forms a depressed surface on the outer surface and the stiffening feature forms a raised surface on the outer surface of the cylindrical casing.

    Abstract: An engine block includes one or more cylinder bores at least partially surrounded by a cylinder bore wall. The cylinder bore wall includes a liner stop mechanism to support a liner in the cylinder bore. The engine block has an outer cylinder block wall that is exterior to the cylinder bore wall. The outer cylinder block wall includes at least one rib located relative to the liner stop mechanism to reduce rotation and buckling of the liner during operation of the engine.

    Abstract: An engine block includes one or more cylinder bores wherein each cylinder bore is surrounded by a cylinder bore wall. The cylinder bore wall includes a liner stop mechanism to locate a liner in the cylinder bore. The cylinder bore includes a mid-portion that spans between an upper end and a lower end, wherein the liner stop mechanism can be located near the upper end, near the lower end, or the mid-portion. The engine block has an outer cylinder block wall that is exterior to the cylinder bore wall. The outer cylinder block wall includes a first rib positioned above the liner stop mechanism and a second rib positioned below the liner stop mechanism relative to a cylindrical axis of the cylinder bore. The first and second ribs straddle the liner stop mechanism to reduce rotation and buckling of the liner during operation of the engine.

    Abstract: An engine block, an engine subassembly, and method for providing and manufacturing an engine block. The engine block includes a plurality of cylinder barrels positioned in the engine block, at least one oil jacket channel formed in the engine block, and an oil inlet port positioned in a peripheral wall of the engine block and connected to the at least one oil jacket channel. The at least one oil jacket channel includes a plurality of curved channel sections. Each curved channel section in the plurality of curved channel sections extends about at least a portion of a circumferential portion of a respective cylinder barrel in the plurality of cylinder barrels. The at least one oil jacket channel extends between adjacent cylinder barrels of the plurality of cylinder barrels in the engine block.
