Catalyst Structure

Toyota Motor Corporation announces the commercial availability of a new, smaller catalyst that uses 20% less precious metal in approximately 20% less volume, while maintaining the same exhaust gas purification performance. The design is the world's first integrally-molded Flow Adjustable Design Cell (FLAD®) substrate, with a different cell cross-sectional area at the inner portion compared to that at the outer portion. Innovative design and manufacturing technologies have allowed for the mass production of the new catalyst, which will gradually be installed in new vehicle models, starting from the Lexus LC 500h later this year.
