Internal combustion engine block with cylinder liner decentralized flow cooling system and its cooling method

摘要

It is an internal combustion engine block formed between the cylinder block and the cylinder liner and surrounded adjacent to the hot combustion chamber zone of the engine so that coolant flow is provided to evenly and effectively cool this problematic area of the liner. The flow characteristics of the upper liner cooling channel provide a high speed coolant flow with an aspect ratio of width relative to a height within a predetermined range and a significant diameter within a predetermined range to ensure uniform temperature around both sides of the cylinder liner and the entire perimeter of the liner. Done.
