Abstract

EL CATALIZADOR (1) DE GASES DE ESCAPE CON UNA ESTRUCTURA (10) SOPORTE DISPUESTA PARA EL MATERIAL CATALIZADOR, MUESTRA CAPAS (13) CON CANALES DE FORMA PARALELA. LAS CAPAS ESTAN DIRIGIDAS DE FORMA ESENCIALMENTE PARALELA CON RESPECTO A LA DIRECCION (15) DE CORRIENTE PRINCIPAL DE LOS GASES DE ESCAPE. LAS SUPERFICIES DE SECCION TRANSVERSAL DE LA ESTRUCTURA SOPORTE A LO LARGO DE LA DIRECCION DE CORRIENTE PRINCIPAL MUESTRAN SEGUN LA INVENCION AL MENOS DE FORMA PARCIAL UN CONTENIDO SUPERFICIAL VARIABLE Y/O FORMA VARIABLE; CERRANDO LOS CANALES CONTRA LA DIRECCION DE CORRIENTE PRINCIPAL UN ANGULO ENTRE ALREDEDOR DE 10 Y 70 ONTRA OTRAS Y CRUZANDOSE UNA CON OTRA. EL CATALIZADOR DE GASES DE ESCAPE DE ACUERDO CON LA INVENCION PERMITE LA ADAPTACION EN SU FORMA A RELACIONES DE ESPACIO ESTRECHAS.
