    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: An annular cylinder liner includes an annular body defining a longitudinal axis, a radial direction perpendicular to the longitudinal axis, a circumferential direction, a first longitudinal end, a second longitudinal end, and a liner length measured from the first longitudinal end to the second longitudinal end along the longitudinal axis. The annular body also includes a shoulder that is disposed at the first longitudinal end, defining a shoulder axial thickness measured along the longitudinal axis. A ratio of the liner length to the shoulder axial thickness ranges from 24.0 to 46.0.

    Abstract: A piston-connecting rod assembly for an internal combustion engine includes a piston pivotally mated to a connecting rod by a piston pin. The piston pin includes a first pin end, a second pin end, and a midsection. When assembled, the first pin end and second pin end are respectively received in a first pin bore and second pin on the piston while the midsection is accommodated in a cross-bore through the connecting rod. The piston pin may include a wear resistant layer applied over at least a portion of its external surface that may include at least one of tungsten disulfide and molybdenum disulfide. The wear resistant layer may be applied as part of a manufacturing process performed on the piston pin.

    Abstract translation: 用于内燃机的活塞连杆组件包括通过活塞销枢转地配合到连杆的活塞。 活塞销包括第一销端，第二销端和中部。 当组装时，第一销端和第二销端分别容纳在活塞的第一销孔和第二销中，同时中间部分通过连接杆容纳在十字孔中。 活塞销可以包括施加在其外表面的至少一部分上的耐磨层，其可以包括二硫化钨和二硫化钼中的至少一种。 耐磨层可以作为在活塞销上执行的制造过程的一部分来应用。
