Abstract

EL CATALIZADOR (1) PRESENTA UNA CARCASA (3) CON UNA ENTRADA (3D) ASI COMO UNA SALIDA (3E) Y UN CUERPO DEL CATALIZADOR (7) PERMEABLE AL GAS DISPUESTO EN LA CARCASA (3), CON UNA SUPERFICIE DE ENTRADA DE GASES DE ESCAPE (7A). EN LA CARCASA EXISTE UNA SUPERFICIE CONDUCTORA (15A) ORIENTADA HACIA LA BOCA DE LA ENTRADA (31) A UNA DISTANCIA DE SU BORDE, QUE CON EL EJE (5) CITADO FORMA PREFERENTEMENTE COMO MINIMO UN ANGULO DE 60 (GRADOS) Y COMO EJEMPLO UN ANGULO DE 90 (GRADOS) . LA ENTRADA (3D) POSEE UNA SUPERFICIE INTERIOR CON UNA SECCION CILINDRICA P LIGERAMENTE CONICA (3G), QUE EN LA ZONA DE LA BOCA DE LA ENTRADA (3D), POR MEDIO DE UN CORTE QUE PASA POR EL EJE (5) DE LA ENTRADA (3D) HACIA EL INTERIOR DE LA CARCASA, CON UNA SECCION DE PASO EN FORMA DE ARCO ENSANCHABLE (3H), ESTA UNIDA CONSTANTEMENTE CON UNA SUPERFICIE CONTRARIA (3I) OPUESTA A LA SUPERFICIE CONDUCTORA (15A). EL GAS DE ESCAPE QUE FLUYE POR LA ENTRADA (3D) PUEDE SER DESVIADO MEDIANTE LA SUPERFICIE CONDUCTORA (15A) CON UNA REDUCIDA PERDIDA DE PRESION, Y A CONTINUACION, A TRAVES DE LA SUPERFICIE DE ENTRADA DE GASES DE ESCAPE (7A) DEL CUERPO (7) PUEDE ENTRAR DISTRIBUIDO EN ESTE
