CYLINDER LINER SHUNT FLOW COOLING SYSTEM

摘要

An internal combustion engine block (10) having a circumferential channel (34) formed between the cylinder block (10) and a cylinder liner (14) surrounding and adjacent to the high temperature combustion chamber region (12) of the engine, to which coolant flow is provided to uniformly and effectively cool this critical area of the liner (14). The flow characteristics of the top liner cooling channel (34) 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 side of the cylinder liner (14) and about the entire circumference of the liner (14).
