Abstract
A cooling system for an internal combustion engine eliminate stagnation of a coolant flowing in a plurality of annular passages formed between a cylinder block and a cylinder liner along a circumference of an outer surface of the cylinder linear. Inflow and outflow passages, connected to the annular passages, are provided extending in a direction of an axis of the cylinder liner. An inlet passage, supplying a coolant to the inflow passage, is provided. A guiding member is provided at an entrance of each of the annular passages so as to lead a portion of a coolant to an upstream side of each of the annular passages. Sufficient amount of coolant flows through the annular passages of the cylinder linear, and thus the wall of the cylinder liner can be cooled efficiently.
