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.

An annular cylinder liner comprising:
- 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 including
- a shoulder that is disposed at the first longitudinal end, defining a shoulder axial thickness measured along the longitudinal axis;
- and
- wherein a ratio of the liner length to the shoulder axial thickness ranges from 24.0 to 46.0, and the annular cylinder liner further includes a radially thin portion disposed at the second longitudinal end, the radially thin portion defining a thin radial thickness measured along the radial direction ranging from 3.0 mm to 5.0 mm, and the annular body lacks internal voids.
