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.

Abstract: A lubrication system for an engine is disclosed. The engine has a cylinder block that includes a face portion and an oil gallery. The lubrication system includes one or more oil passages that extend between the oil gallery and the face portion. The oil passages include a lubrication port, a first channel, a second channel, and a third channel. The lubrication port is defined at interface of the oil passages and the face portion of the cylinder block. Each of the first channel, the second channel, and the third channel extends from the previous channel in a sequential manner and has a first end and a second end. The first channel extends in a substantially horizontal direction from the lubrication port. The second channel extends in a substantially vertical direction from the first channel. The third channel is connected to the oil gallery.
