Abstract
A motor vehicle cylinder head is provided with a single flat planar surface in which are formed spaced apart integral inlet and outlet ports used for connecting respective coolant supply and returns to a coolant jacket defined within the cylinder head. The use of a common planar surface for the location of the inlet and outlet ports provides a more reliable sealing of the cylinder head to the respective coolant supply and returns.
Claims19
A cylinder head of an engine having a coolant jacket formed therein for circulating coolant through the cylinder head and a combined inlet and outlet connector formed as an integral part of the cylinder head for connecting the cylinder head to an external coolant system, the combined inlet and outlet connector comprising a flat planar surface defining, in a spaced apart manner, coolant inlet and outlet ports with the inlet port being positioned vertically below the outlet port, wherein a lower surface of the cylinder head is formed by a flame plate of the coolant jacket, and internal supply passages connected to the inlet port are positioned adjacent the flame plate so as to flow coolant over the flame plate, wherein the cylinder head has an exhaust gas manifold formed as an integral part thereof, the exhaust gas manifold exiting at a side of the cylinder head via an exhaust system mount having a flat exterior planar surface, the flat planar surface of the combined inlet and outlet connector arranged perpendicular to the flat exterior planar surface of the exhaust system mount and at the side of the cylinder head.
An engine having a cylinder block to which is sealingly secured to a cylinder head, wherein the cylinder head has a coolant jacket formed therein for circulating coolant through the cylinder head, and a combined inlet and outlet connector formed as an integral part of the cylinder head for connecting the cylinder head to an external coolant system, the combined inlet and outlet connector comprising a flat planar surface defining, in a spaced apart manner, coolant inlet and outlet ports with the inlet port being positioned immediately vertically below the outlet port, wherein a lower surface of the cylinder head is formed by a flame plate of the coolant jacket, and internal supply passages connected to the inlet port are positioned adjacent the flame plate so as to flow coolant over the flame plate, wherein the cylinder head has an exhaust gas manifold formed as an integral part thereof, the exhaust gas manifold exiting at a side of the cylinder head via an exterior planar surface of an exhaust system mount, the flat planar surface of the combined inlet and outlet connector arranged perpendicular to the exterior planar surface of the exhaust system mount and at the side of the cylinder head.
An article, comprising:
- an engine cylinder head with a coolant jacket and a combined inlet and outlet connector integrally formed with the head connecting the head to an external-to-the-engine coolant system, the connector having a flat planar surface defining a coolant inlet immediately vertically below an outlet port, a lower surface of the head formed by a coolant jacket flame plate, internal supply passages connected to an inlet port being positioned adjacent the flame plate, wherein the head has an exhaust gas manifold formed as an integral part thereof, the exhaust gas manifold exiting at a side of the head via an exhaust system mount having a flat surface, a flat surface of the connector arranged perpendicular to the flat surface of the exhaust system mount, and the connector positioned at a corner of the side of the head.
