[Abstract] The car is one that is not possible to separate from our life. However, an increase of automobile emissions causes air pollution and acid rain, which becomes a environmental problem. To solve this problem, the development of the eco-car is needed. The converter is a device that makes a hazardous substance from the automobile emissions reacting to a catalyst chemically, and makes it comparatively converted into a harmless substance. The vehicle exhaust emission has concentrated on the center part of the converter generally used now. The automobile emission doesn't flow to the wall side of the converter so much. Therefore, the catalyst in the converter is not efficiently used. If the automobile emission passes uniformly through the converter, the catalyst is used efficiently. In addition, the cost of expensive catalyst can be saved by decrease in amount of using. In this paper, the flow of the automobile emission was verified by the difference of the manifold converter shape in the numerical simulation. The converter that made the automobile emission reacting efficiently to the catalyst was designed.
