Abstract

UN SISTEMA, Y UN METODO CORRESPONDIENTE, PARA DETECTAR LA PRESENCIA DE UN ESTADO DE FALLO EN EL ENCENDIDO MEDIANTE LA INTERPRETACION DE LA ACTIVIDAD ESPECTRAL DE UN MOTOR EN FUNCIONAMIENTO QUE INCLUYE UN DISPOSITIVO (309, 313) PARA MEDIR UNA CARACTERISTICA, PREFERENTEMENTE UNA CARACTERISTICA DE ACELERACION, INDICATIVA DEL COMPORTAMIENTO DEL MOTOR EN FUNCIONAMIENTO. UN FILTRO PROGRAMABLE (701) DEPENDIENTE DE UNA VELOCIDAD DETERMINADA DEL MOTOR (335) PROPORCIONA UNA SEÑAL DE ACELERACION FILTRADA (703) QUE RESPONDE A UNA SEÑAL DE ACELERACION (317) PROPORCIONADA POR EL DISPOSITIVO MEDIDOR DE LA ACELERACION (309, 313). UN DISPOSITIVO DE DISCRIMINACION ESPECTRAL (319), PREFERENTEMENTE UN FILTRO DIGITAL, RECIBE LA SEÑAL DE ACELERACION FILTRADA (703) PROPORCIONADA POR EL FILTRO PROGRAMABLE (710). EL FILTRO DIGITAL (319) PROPORCIONA UN SEÑAL DE ENCENDIDO NORMAL (321), CORRESPONDIENTE A LA ENERGIA ESPECTRAL ATRIBUIBLE A UNA PORCION DE LA SEÑAL COMPUESTA (317) REPRESENTATIVA DE UN ESTADO DE ENCENDIDONORMAL DEL MOTOR EN FUNCIONAMIENTO, Y UNA SEÑAL DE FALLO EN EL ENCENDIDO (323), CORRESPONDIENTE A LA ENERGIA ESPECTRAL ATRIBUIBLE A OTRA PORCION DE LA SEÑAL COMPUESTA (317) REPRESENTATIVA DE UN ESTADO DE FALLO EN EL ENCENDIDO DEL MOTOR EN FUNCIONAMIENTO. UN DISPOSITIVO DE COMPARACION (325) PROPORCIONA E INDICA UN ESTADO DE FALLO EN EL ENCENDIDO (327) CUANDO UNA MAGNITUD DE LA SEÑAL DE FALLO EN EL ENCENDIDO (323) SOBREPASA UNA MAGNITUD DE LA SEÑAL DE ENCENDIDO NORMAL (321).
