    摘要： An exhaust manifold in which a plurality of branch tubes at an inlet side are connected to a collecting tube at an outlet side, and in which the fluid flows from the branch tubes to the collecting tube, wherein a volumetric chamber is provided between at least a pair of the branch tubes in communication with the branch tubes, with the volumetric chamber being gradually increased in its cross-sectional area in a fluid flowing direction. An exhaust manifold formed of upper and lower members comprises a branch tube having a bend. The upper lower members are interconnected by joining flanges having a broader width in the vicinity of the bend than other joining flange portions.

    摘要： An exhaust manifold has a plurality of double pipes, each of which includes an inner pipe and an outer pipe, and a collecting pipe to which each of the double pipes is connected. The outer peripheral portion of the outer pipe is secured to the collecting pipe, and a thermal insulating layer of air, which is formed as a closed space so that substantially no exhaust gas will penetrate it, is disposed on an inner peripheral side of the portion at which the outer periphery of the outer pipe is secured to the collecting pipe. Owing to the presence of the thermal insulating layer, heat is not transmitted to the welded joint directly via the inner and outer pipes.
