Abstract
An internal combustion engine exhaust manifold has a lateral opening through which exhaust gases may heat intake mixtures for the engine. The exhaust manifold comprises a thick wall housingg enclosing a thin wall liner, the liner having inlet tubes receiving exhaust gases from the engine exhaust ports, and having a discharge pipe. The liner is secured in the lateral opening of the housing so that its inlet tubes and discharge pipes may move by differential expansion. Internally threaded sockets fixed to the liner extend into the housing opening and the sockets project through clearance openings in a stationary support ring fixed to the housing opening. Threaded fasteners are received in the sockets and a heat shield is mounted within the liner to prevent exposure of the ends of the threaded fasteners to the hot exhaust gases within the liner.
