Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA SUPERVISION DE UN FUNCIONAMIENTO DE UN CONVERTIDOR (3) CATALITICO PARA PURIFICACION DE GASES DE EXHAUSTACION, DISPONIENDO DE UNA ESTRUCTURA (4) DE SOPORTE Y UNA COBERTURA ACTIVA CATALITICAMENTE ADHESIVA SOBRE LA ESTRUCTURA (4) DE SOPORTE, COLOCADA POR DEBAJO DEL MOTOR (1) DE COMBUSTION INTERNA DE UN VEHICULO A MOTOR, COMPRENDIENDO LAS SIGUIENTES ETAPAS: (A) DETERMINACION DE LA TEMPERATURA (TK) DEL RECUBRIMIENTO (5) ACTIVO CATALITICAMENTE Y/O LA ESTRUCTURA (4) DEL CONVERTIDOR (3) CATALITICO EN AL MENOS UN PUNTO; (B) DETERMINACION DE LA TEMPERATURA (TG) DEL GAS DE EXAHUSTACION POR ENCIMA DE ESTE PUNTO EN EL CONVERTIDOR (3) CATALITICO; ENCUENTRO AL MENOS DEL PRIMER TIEMPO DE DERIVACION DE AMBAS TEMPERATURAS (8); (C) ENCUENTRO DE LAS DIFERENCIAS ENTRE LAS DERIVACIONES DE TIEMPO (9); (D) DETERMINACION DEL TIEMPO DESPUES DE ARRANCADO DEL MOTOR DE COMBUSTION INTERNA EN EL CUAL LA DIFERENCIA CAMBIA DE SITIO (12). EL PROCESO PERMITE UNA DETECCION PRONTA DE FUNCIONAMIENTO DEFECTUOSO EN UN CONVERTIDOR (3) CATALITICO, EN PARTICULAR EN LO QUE SE REFIERE A SU COMPORTAMIENTO EN ARRANQUE EN FRIO.
