Abstract
In a cooling structure of a cylinder block, a cooling medium is supplied into the cylinder block in which a water jacket continuously extends around a bore wall, so as to uniform the bore wall temperature. The cooling structure sets a cooling characteristic of the water jacket based on at least one of variation in the bore wall temperature in a direction perpendicular to the axis of the borehole and variation in the temperature of the cooling medium flowing around the bore wall. The structure improves the cylinder bore cooling efficiency or the cooling uniformity.
