Toyota's new exhaust purifying catalyst reduces precious metal usage

By CARSIFU | 23 February 2017


TOYOTA CITY: Toyota Motor Corp has announced 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.

The new catalyst will gradually be installed in new vehicle models, starting from the Lexus LC 500h later this year.

Increased usage of catalytic precious metals to clean exhaust gas and reduce air pollution presents many issues, including increased costs and resource depletion.

Toyota and Denso Corp have developed this new FLAD substrate to improve the uniformity of exhaust gas flow.

The newly developed innovative design and manufacturing technologies have also allowed for the mass production of the world's first integrally molded catalyst.
