Air Shielded Water Cooled Exhaust Manifold With Exhaust Tube Support |
| 摘要 |
An internal combustion engine includes a cylinder block defining at least one cylinder, and a cylinder head coupled to the cylinder block. An exhaust manifold is coupled to the cylinder head and configured to receive exhaust gas from the cylinder head. The exhaust manifold includes a water jacket tube defining a plurality of liquid coolant passages and an exhaust tube received within the water jacket tube. The exhaust manifold also includes an air gap between the exhaust tube and the water jacket tube. A support mat is positioned in the air gap and compressed between an outer surface of the exhaust tube and an inner surface of the water jacket tube. |
