Abstract

SE DESCRIBE UN CONVERTIDOR CATALITICO QUE TIENE DOS O MAS MATRICES (10A,10B) CADA UNA DEFINE UNAS CRUJIAS PARA LOS GASES DE ESCAPE Y TRANSPORTAN LAS PARTICULAS DE UN CATALIZADOR. LAS MATRICES SE SITUAN EN SERIES UNAS CON OTRAS EN LA DIRECCION DEL FLUJO DE GAS A TRAVES DEL CONVERTIDOR. UNA CAMARA (16) DISPUESTA ENTRE AMBAS MATRICES CONTIENE UN INFLAMADOR (18) PARA INFLAMAR EL GAS EN LA CAMARA Y FORMAR UN DISPOSITIVO DE POSTCOMBUSTION QUE CALIENTA LA SEGUNDA DE LAS MATRICES QUE REDUCE EL TIEMPO NECESARIO PARA QUE ESTA ALCANCE SU TEMPERATURA DE APAGADO.
