Abstract
A water-jacket structure, for a water-cooled internal combustion engine, forms a cylinder block water jacket in a cylinder block so as to surround cylinder bores formed in the cylinder block to make cooling water flow through the cylinder block water jacket into a cylinder head water jacket formed in a cylinder head joined to the cylinder block. An upper connecting opening is formed in an upper part of the cylinder block water jacket so as to open into the cylinder head water jacket. In the cylinder block is formed a lower connecting passage opening into a lower part of the cylinder block water jacket, extending upward, and connecting to the cylinder head water jacket.
