Abstract (en)
[origin: JPH0318611A] PURPOSE: To avoid gas dynamic reaction even in the case where a catalyst is arranged in the vicinity of an internal combustion engine by arranging a center wall covered by a catalyst extending in an exhaust flow direction between metallic thin plate shells. CONSTITUTION: A part 2 constituted as a diffuser which is bent and directly connected to an internal combustion engine, is composed of two connected metal thin plate shells 3. A center part 5 wherein a main catalyst 6 is arranged is connected to the part 2 of an exhaust system. A center wall 7 which extends in an exhaust flow direction and which is covered with the catalyst is arranged between both metallic thin plate shells 3. Since the center wall 7 as the catalyst not obstruct gas dynamic reaction, the catalyst can be arranged in the vicinity of the internal combustion engine 1.
