Title: Water-cooled internal combustion engine

Abstract: In a water-cooled internal combustion engine with a cooling water path extending from a supply passage at one side of the engine through cooling water spaces around the engine cylinders to the cylinder head and back to a cooling water return channel at the other side of the engine, a separate annular cooling water channel extends around each cylinder adjacent the combustion chamber and this annular cooling channel is supplied by cooling water in a flow path parallel to the flow path through the cylinder head so as to provide for adequate cooling of the cylinders adjacent the combustion chambers.
