Reinforced exhaust manifold

摘要

The manifold has a wall (10) having thickness at a level of a sealing surface of a foundry of a fastening clip (30) of the manifold. A reinforcement element (13) includes an outer wall (10') incorporated into the wall (10) of the manifold. The outer wall and an inner wall (14) of the element are separated from each other by an insulation layer (15), where the element is molded by casting with the manifold. The insulation layer is opened on the fastening clip.
