An engine cylinder head has an exhaust manifold cast in the cylinder head. A turbocharger with a turbine body is adapted to mount directly to an exhaust outlet mounting face of the exhaust manifold. A dual level water jacket within the cylinder head has separate coolant feeds for upper and lower cooling jackets. The cooling jackets extend above and below the exhaust outlet and are connected inward of the exhaust mounting face to reduce metal temperatures of the mounting face below those of the turbocharger exhaust inlet flange. Separate cores for the upper and lower jackets are connected at coolant inlet and outlet locations at opposite ends. Intermediate core print connectors form controlled flow passages between the upper and lower jackets and exhaust ports in the cylinder head and integrated manifold. The improved cooling in these areas lowers operating temperatures in the cylinder head and obviates the need for a separate exhaust manifold.

An insert for a siamese-type internal combustion engine that separates a water jacket surrounding the cylinders into an upper portion and a lower portion. Below a predetermined engine speed coolant flows primarily in the upper water jacket portion so as to provide enhanced cooling at the upper portions of the cylinders. Above a predetermined engine speed coolant is introduced into the lower water jacket portion from the upper water jacket portion so as to provide improved cooling of the lower cylinder portions, without compromising cooling of the upper cylinder portions or the conjoined cylinder wall portions. The water jacket insert enhances coolant flow velocity at the siamesed or conjoined portions of the cylinder walls, and directs incoming initially coolant over the exhaust-side of the cylinders. Use of the insert reduces circumferential and axial intra-cylinder temperature deviations as well as inter-cylinder temperature deviations.

In a cylinder head, a cooling water passage with a circular shape (an elliptical shape) in cross section in radial direction is formed at an area (lower layer deck) closer to a combustion chamber than a water jacket in which a cooling water flows. The cooling water passage of the cylinder head is formed by casting by providing a hollow core in a mold and removing the hollow core.

The position of a passage separating member in the axial direction of the cylinder bores is determined by causing a spacer to contact a bottom surface of a water jacket. When the separating member is inserted in the water jacket, the width of the separating member is reduced due to elastic deformation, so that the separating member can be arranged in the water jacket. After being arranged, the separating member tightly contacts the inner surface of the water jacket due to elastic restoration force. The tight contact prevents the separating member from moving upward in the water jacket. As a result, coolant is prevented from moving between the upper portion and the lower portion with respect to the separating member. The advantages of separate cooling of the coolant in the upper and lower portions with respect to the separating member are obtained. This reliably reduces the temperature difference along the axial direction of the cylinder bore forming body.
