Abstract
A cooling system for an internal combustion engine able to realize a cooling effect matching a distribution of incoming heat of a cylinder liner. A plurality of annular grooves are formed on an outer surface of the cylinder liner, and a passage connecting the annular grooves is also provided. An introducing passage part is formed between an inlet passage of a coolant and the uppermost annular groove. A curved portion is provided to the introducing passage part. A flow direction of the coolant flowing into the introducing passage part is smoothly changed so as to flow along a direction of a passage connecting the annular grooves. An amount of coolant flowing into the annular grooves located lower than the uppermost annular groove is increased appropriately.
