Internal combustion engine block having a cylinder liner shunt flow cooling system and method of cooling same

摘要

An internal combustion engine block having a circumferential channel formed between the cylinder block and a cylinder liner, surrounding and adjacent to the high temperature combustion chamber region of the engine, to which coolant flow is provided to uniformly and effectively cool this critical area of the liner. The flow characteristics of the top liner cooling channel provide a high velocity coolant stream having an aspect ratio of width relative to height within a predetermined range and an equivalent diameter within a predetermined range to assure uniform temperature on both sides of the cylinder liner and about the entire circumference of the liner.
