Abstract

DISPOSICION DE CATALIZADOR PARA LA LIMPIEZA DE GASES DE EXHAUSTACION DE MOTORES DE COMBUSTION INTERNA, EN PARTICULAR MOTORES DE IGNICION, CON AL MENOS UN PRIMER CATALIZADOR (2) PARCIAL, AL MENOS UN SEGUNDO CATALIZADOR (4) PARCIAL Y UN DISPOSITIVO (3) DE CALENTAMIENTO ELECTRICO ENTRE EL PRIMER (2) Y EL SEGUNDO (4) CATALIZADORES PARCIALES. LA DISPOSICION DE LA INVENCION HACE PARTICULARMENTE BUEN USO DE LA POTENCIA ELECTRICA UTILIZADA PARA EL CALENTAMIENTO Y ES INSENSIBLE AL ENVEJECIMIENTO Y A LA CONTAMINACION DURANTE LARGOS PERIODOS OPERATIVOS. EL DISPOSITIVO (3) DE CALENTAMIENTO PUEDE ESTAR INSERTADO ENTRE CATALIZADORES (2,4) PARCIALES CERAMICOS O DE METAL Y DISPONE ASIMISMO DE UNA ESTRUCTURA METALICA EN FORMA DE PANAL QUE PUEDE SER CALENTADA ELECTRICAMENTE DE FORMA DIRECTA, PREFERENTEMENTE CON UNA CANTIDAD DE CELDAS DESDE 50 HASTA 200 CPI. LA DISPOSICION DE CATALIZADOR ESTA DISEÑADA PARA REDUCIR LA EMISION DE POLUCION EN LA FASE DE ARRANQUE EN FRIO DE UN MOTOR DE COMBUSTION INTERNA CON LA MISMA EFICIENCIA DURANTE UN LARGO PERIODO DE VIDA UTIL.
