Embodiment Construction

[0016] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In some cases, reference numbers will be indicated in this specification, and the drawings will show a reference number followed by a letter (eg 100a, 100b) or a prime sign (such as 100' , 100", etc.). It should be understood that the use of a letter or prime designation immediately following a reference number is to indicate that these features have similar shape and similar function, which is usually the case when the geometry is mirrored about the plane of symmetry. For convenience Explained in this specification, letters or apostrophes are often not included in the text, but may be shown in the drawings, so as to indicate that this is a reproduction of features discussed in this written specification.

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 along the longitudinal axis from the first longitudinal end to the second longitudinal end. The annular body further includes a shoulder disposed at the first longitudinal end defining a shoulder axial thickness measured along the longitudinal axis. A ratio of the bushing length to the shoulder axial thickness ranges from 24.0 to 46.0.

Description

technical field [0001] The present disclosure generally relates to a cylinder liner for an internal combustion engine having a piston that slides back and forth within the cylinder liner. More specifically, the present disclosure relates to cylinder liners that allow for proper clearance when employing other engine components having altered geometries. Background technique [0002] Internal combustion engines are commonly used in a variety of industries to power machines and equipment. Examples of industries that use such machines and equipment include the marine, earth moving, construction, mining, locomotive, and agricultural industries. Internal combustion engines that require less maintenance and / or provide more power are desirable in certain markets and market segments. [0003] More specifically, various engine components, including cylinder liners, often need to be replaced because as they wear, the engine may develop problems. In a compression ignition engine, mor...
