EXHAUST INSERT FOR EXHAUST PORT

摘要

An exhaust insert for use with an internal combustion engine transfers heat from exhaust gases to a liquid-cooled exhaust manifold. One end of the exhaust insert extends into the exhaust port of a cylinder head, and the other end of the exhaust insert extends into an exhaust manifold. Exhaust gases are received from the cylinder head by the exhaust manifold through the exhaust insert. The exhaust insert is in contact with a surface of the exhaust manifold so as to transfer heat from the exhaust gases away from the cylinder head to the exhaust manifold.
