Abstract (en)
The manifold comprises a bedplate (10), which is fixed to the cylinder head (50), and a tube (20) formed by the external wall (21) and an internal wall (22). The tube edges (211,221) are assembled on the base plate. A fibre ceramic material (30) forms a thermal radiation shield between the external and internal walls. The edges (211) of the external wall are assemble on the base plate by a weld (40) without metal. The edges of the external wall are placed against an internal chamfer in the base plate. The edges of the internal wall are pressed against the edges of the external wall and separated by an insulating material. The internal and external walls are conformed to form a thermal shield for the weld.
