Abstract: A piston for an internal combustion engine includes a piston body forming a crown portion and a skirt portion. The skirt portion includes a bore that is arranged to receive a pin for connecting the piston to a connecting rod. The crown portion forms a bowl surrounded by a flat crown surface having an annular shape. The bowl and flat crown surface meet along a circular edge surrounding a rim of the bowl. The piston further includes an annular protrusion disposed within the bowl adjacent the rim. The annular protrusion has a generally convex shape in cross section that is created by an upper, inwardly extending surface and a lower, inwardly extending surface, which meet along a convex apex.

Abstract: A cylinder liner assembly is disclosed for use with an engine. The cylinder liner assembly may have a liner with a hollow, generally cylindrical body extending from a top end to a bottom end along a longitudinal axis. The cylinder liner assembly may also have a seal disposed around the liner at the top end and an anti-polishing ring disposed within the top end of the liner. The anti-polishing ring may have an annular groove formed on an outer surface to provide an air gap between the anti-polishing ring and the liner. The annular groove may axially overlap at least a portion of the seal.
