Abstract
An internal combustion engine includes a cylinder block with a cylinder bore. A cylinder liner within the cylinder bore has a distal end with an outside diameter. A cooling ring has a first inside diameter, a larger second inside diameter and a plurality of radial coolant passages. The first inside diameter is positioned closely adjacent to the outside diameter at the distal end of the cylinder liner. The second inside diameter is radially spaced apart from and defines an annular coolant channel with the outside diameter of the cylinder liner. The radial coolant passages are in fluid communication with the annular coolant channel.

An internal combustion engine, comprising:
- a cylinder block having a cylinder bore;
- a cylinder liner within said cylinder bore, said cylinder liner having a distal end with an outside diameter;
- and
- a cooling ring having a first inside diameter, a larger second inside diameter and a plurality of radial coolant passages, said first inside diameter positioned closely adjacent said outside diameter at said distal end of said cylinder liner, said second inside diameter being radially spaced apart from and defining an annular coolant channel with said outside diameter of said cylinder liner, said radial coolant passages being in fluid communication with said annular coolant channel.
A cooling ring positionable between a cylinder bore and a cylinder liner in an internal combustion engine, said cooling ring comprising:
- a ring-shaped body having a first inside diameter, a larger second inside diameter, an outside diameter and a plurality of radial coolant passages, each of said radial coolant passages extending from said second inside diameter to said outside diameter and positioned adjacent to said first inside diameter.
