The application of catalytic converters is the most cost-efficient way to meet stricter motorcycle emission standards. This paper attempts to evaluate the catalyst performance for motorcycles in Taiwan, Europe, and India over the ECE-R40, ECE-R47 and Indian Drive Cycle. Results of simulated exhaust system and vehicle tests indicate that the light-off performance and thermal stability of Pd/Pt-perovskite and Pd/Pt/Rh-perovskite catalysts are better than those of the conventional Pt/Rh catalyst. Perovskite oxide with precious metals gives higher activity and durability and copes better with the stricter motorcycle emissions regulations expected in the future. As perovskite oxide enhances the activity of precious metal, less precious metal is required, resulting in a significant cost reduction.
