Abstract

SEGUN LA INVENCION, A) SE COLOCA UNA SONDA DE OXIGENO (12) CUYA SEÑAL DE SALIDA CONMUTA ENTRE DOS NIVELES, EN LA CORRIENTE DE GAS QUE SALE DEL CONVERTIDOR CATALITICO (11), B) DURANTE LA REGULACION, Y A UNA VELOCIDAD ESTABILIZADA, SE CALCULA EL TIEMPO DE INYECCION ADECUADO PARA ASEGURAR LA ESTEQUIOMETRIA DE LA MEZCLA DE AIRE Y COMBUSTIBLE, C) A CONTINUACION SE IMPONE, DURANTE UN INTERVALO DE TIEMPO PREDETERMINADO (DELTA T), UNA VARIACION EN FUNCION AL TIEMPO DE DESVIACION SIMETRICA CUYA AMPLITUD Y FORMA SE PREDETERMINAN A PARTIR DE UN TIEMPO DE INYECCION BASE SELECCIONADO DEL TIEMPO DE INYECCION DETERMINADO EN EL PASO B), D) SE MODIFICA PROGRESIVAMENTE EL TIEMPO DE INYECCION BASE DURANTE INTERVALOS DE TIEMPO SUCESIVOS Y DE UNA MANERA MONOTONICA PARA CENTRAR ASI LA DESVIACION DEL TIEMPO DE INYECCION RESPECTO A LA CAPACIDAD DE ALMACENAMIENTO DE OXIGENO DEL CONVERTIDOR CATALITICO Y E) DEL POSIBLE ASPECTO DE UNA OSCILACION DE ESTA SEÑAL SE EVALUA EL RENDIMIENTO DEL CATALIZADOR. LA INVENCION SE PUEDE APLICAR A LOS MEDIOS DE DIAGNOSTICO INSTALADOS EN UN VEHICULO DE MOTOR.
