Abstract

SE PRESENTA UN PROCESO PARA LA VIGILANCIA EN SERVICIO DE LAS CARACTERISTICAS DE UN CATALIZADOR (8) PARA GASES DE ESCAPE DE UN MOTOR (1) DE COMBUSTION INTERNA CON UN SISTEMA (5, 8, 9) DE GASES DE ESCAPE, DONDE LA TEMPERATURA EN DOS ZONAS DE LA SECCION TRANSVERSAL SEPARADAS EN CUANTO AL ESPACIO EN EL SISTEMA DE GASES DE ESCAPE SE MIDE POR MEDIO DE SENSORES DE TEMPERATURA (TF1, TF2; TF1, TF2,), Y SON MONITORIZADOS CON UN DISPOSITIVO (10) ELECTRONICO. AL MENOS UNA PARTE DEL VOLUMEN DEL CATALIZADOR QUE ES ESENCIAL PARA LA CONVERSION CATALITICA DE SUSTANCIAS NOCIVAS EN LOS GASES DE ESCAPE SE LOCALIZA ENTRE LOS DOS PUNTOS DE MEDIDA. LOS SENSORES DE TEMPERATURA (TF1, TF2) NO MIDEN DISCRETAMENTE PERO SI DE FORMA INTEGRAL EN UNA PARTE REPRESENTATIVA DE LA ZONA DE SECCION TRANSVERSAL. LOS PUNTOS DE MEDIDA DE TEMPERATURA PUEDEN SER INTEGRADOS EN EL CATALIZADOR (8), QUE PUEDE SER TAMBIEN DE FORMA PREFERENTE CALENTADO ELECTRICAMENTE (17, 18). EN UN SISTEMA PROPIAMENTE EN FUNCIONAMIENTO, PUEDE SER MONITORIZADA LA REACCION EXOTERMICA EN LA CONVERSION CATALITICA DE SUSTANCIAS NOCIVAS EN LOS GASES DE ESCAPE EN CIERTAS TEMPERATURAS DIFERENTES ENTRE DOS PUNTOS DE MEDIDA. LA FUNCION DEL CATALIZADOR (8) Y/O MOTOR (1) Y/O SISTEMA (2) DE CONTROL DEL MOTOR ELECTRONICO PUEDEN SER DEDUCIDA DE LA SEÑAL Y/O VALOR ABSOLUTO Y/O VARIACION TEMPORAL DE LA DIFERENCIA DE TEMPERATURAS. CAMPOS PREFERENTES DE APLICACION: VEHICULOS A MOTOR CON MOTORES DE IGNICION DE CHISPA CON UN SISTEMA DE CONTROL DE MOTOR ELECTRONICO.
