Abstract

A cooling structure of a multi-cylinder engine is provided, which includes cylinder bores formed in a cylinder block, a water jacket surrounding the bores, a cylinder head, and a water jacket spacer accommodated in the water jacket and having a peripheral wall formed corresponding to the cylinder bores. A length of the peripheral wall in cylinder bore axial directions is substantially the same as that of the water jacket. The peripheral wall forms, inside the water jacket, inner and outer channels, and a width of the inner channel is less than that of the outer channel. Communicating holes communicating the inner and outer channels are formed in the peripheral wall at locations between adjacent cylinder bores, respectively. Inter-bore channels into which some cooling fluid flowing from the outer channel into the inner channel flows are provided to parts of the cylinder block between the adjacent cylinder bores, respectively.
