Abstract

UN DISPOSITIVO DE LIMPIEZA DE GAS DE ESCAPE ESTA COLOCADO EN UN TUBO DE ESCAPE (3) CONECTADO A UN PUERTO DE ESCAPE (2) DE UN MOTOR DE COMBUSTION INTERNA (1). EL DISPOSITIVO DE LIMPIEZA DE GAS DEL ESCAPE COMPRENDE UN TUBO INTERNO (5) DISPUESTO COAXIALMENTE EN EL TUBO DE ESCAPE (3) CON UN ESPACIO (4), EL TUBO INTERNO (5) ESTA PROVISTO CON UNA SERIE DE PERFORACIONES (6), Y ESTRUCTURAS DE CAPAS DISPUESTAS SOBRE SUPERFICIES INTERNAS Y EXTERNAS DEL TUBO INTERNO (5) E INCLUYENDO UN CATALIZADOR (8) PARA LIMPIEZA DE UN COMPONENTE NO QUEMADO DEL GAS DE ESCAPE QUE FLUYE EN EL TUBO DE ESCAPE (3), ESTANDO FORMADA CADA UNA DE LAS ESTRUCTURAS DE CAPAS DE UN MATERIAL QUE TIENE UNA PROPIEDAD NO VENENOSA PARA EL CATALIZADOR. LA ESTRUCTURA DE CAPAS INCLUYE UNA CAPA PORTADORA DE CATALIZADOR (8) FORMADA, EN UN METODO, POR MECHA DE INYECCION DE UN CATALIZADOR, INCLUYENDO SOLUCION (8) SOBRE UNA CAPA INTERMEDIA (7) FORMADA SOBRE LAS SUPERFICIES INTERNA Y EXTERNA DEL TUBO INTERIOR (5) Y SECANDO EL MISMO PARA ELIMINAR EL COMPONENTE LIQUIDO. LA ESTRUCTURA DE CAPAS (7,8) PUEDE ESTAR FORMADA SOBRE LA SUPERFICIE INTERNA DEL TUBO DE ESCAPE (3) PARA MEJORAR EL EFECTO DE LIMPIEZA DEL GAS DE ESCAPE.
