Abstract
An exhaust manifold including a manifold body made of a first material and at least one heat shield insert provided inside the manifold body and made of a second material. The first material is a low cost material and the second material is a higher grade, temperature-resistant material. The manifold body includes a plurality of runners, collector and an outlet. The shield insert is preferably provided in the collector region adjacent to the outlet. The heat shield insert may have a curved sheet configuration or a tubular configuration depending on applications. The heat shield properly insulates the manifold body from the exhaust gas to protect the manifold body. The exhaust manifold, which is made from a combination of different materials, provides a more cost-effective solution in high temperature applications.
