Abstract
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 diverted from the main coolant stream to uniformly and effectively cool this critical area of the liner. The high velocity flow of the main coolant stream, as it passes the end of the cylinder liner adjacent the combustion chamber, provides a reduced pressure head at the port interconnecting the outlet end of the circumferential channel with the main coolant stream. Channel entrance holes, located upstream at relatively stagnant regions in the main coolant flow, are at a higher pressure head than the channel exit port, thus inducing flow through the channel at a high velocity flow.
