Abstract

This research represents the catalytic converter for application in the motorcycle. Present research model type is monolithic catalytic converter and this type have been widely used for satisfaction on and the regulations of pollutant emissions in automobiles. The flow characteristics in a single monolith automotive catalytic converter were investigated by using a computational simulation method without chemical reaction. So we limit the discussion to the effect of flow uniformity in the catalytic converter. Simulation result shows that the flow uniformity of megaphone type catalytic converter is higher than that of a base type. Therefore, the megaphone type is more suitable to motorcycle.
