What Are the Optimal Temperature Ranges for Catalytic Converters?
The optimal temperature range for catalytic converters varies based on the type of catalyst material used. Typically, three-way catalysts, commonly used in gasoline engines, operate efficiently between 300°C to 400°C. For diesel oxidation catalysts, the range is slightly higher, between 250°C to 500°C. Advanced catalysts, such as SCR systems used for reducing nitrogen oxides, usually require temperatures between 200°C to 450°C.
