Abstract
A cooling structure of an engine is provided, which includes a water jacket formed in a cylinder block to surround a cylinder bore of the engine, a spacer having a vertical wall surface and inserted into the water jacket, and a coolant inlet formed in an outer wall of the water jacket, and for circulating to the water jacket coolant introduced from the coolant inlet. The vertical wall surface surrounds the cylinder bore. The spacer includes a guide part provided at a position of a lower end part of the vertical wall surface corresponding to the coolant inlet, and for guiding the coolant introduced from the coolant inlet to flow around the vertical wall surface. The guide part extends outwardly from the lower end part of the vertical wall surface toward the coolant inlet along a bottom wall of the water jacket.
