ク。 A cooling water chamber is formed on the outer periphery of the cylinder by the core of a hollow tubular body made of aluminum alloy that is inserted into the die casting mold and integrally enveloped after casting. One end communicates with the cooling water chamber and the other end opens at the joint surface with the cylinder head by a projection on the die-casting mold that is fitted into an opening provided in the cylinder and removed after casting. An aluminum alloy die-cast cylinder block characterized in that a suitable number of cooling water passages extending in the cylinder axis direction are formed.
