| 摘要 |
The subject invention is a cooling system of an internal combustion engine having a wet-sleeve cylinder liner that improves heat reduction efficiency as compared with traditional cylinder liners. The improved liner has an outer surface with a plurality of peaks and valleys. The peaks and valleys create an increased surface area of the outer surface thereby increasing contact with a cooling medium and more efficiently reducing heat within the engine. The peaks and valleys are positioned along the entire length of the cylinder liner and are generally arcuate in a sinusoidal pattern. The liner also includes an inner surface of the liner that remains generally planar for receiving a piston. Finally, one end of the liner also includes a flange for mating the liner to a counterbore of the engine.
