Abstract

This invention relates to a cooling structure for cooling a cylinder liner by circulating coolant in a water jacket formed along an outer periphery of the cylinder liner. This cooling structure includes an annular first water reservoir for temporarily storing coolant. This first water reservoir allows the coolant to uniformly flow circumferentially of the cylinder liner. The cooling structure also includes a plurality of coolant passages provided radially for connecting the first water reservoir to the water jacket. The coolant is caused to strike a part of a wall defining the water jacket substantially vertically from the radial coolant passages, thereby to generate turbulent flow in the coolant to efficiently cool the cylinder liner.
