Abstract

Filtros de partículas catalizados comprenden material catalítico para la conversión de tres vías (TWC), que comprende rodio como el único metal del grupo del platino, que permea las paredes de un filtro de partículas. Tales filtros de partículas catalizados pueden estar situados corriente abajo de compuestos para la conversión en tres vías de (TWC) de acoplamiento cerrado en un sistema para el tratamiento de las emisiones situado corriente abajo de un motor de inyección directa de gasolina para el tratamiento de una corriente de escape que comprende hidrocarburos, monóxido de carbono, óxido de nitrógeno y partículas.
