Abstract

SE DESCRIBE UN DISPOSITIVO Y UN METODO PARA EL DIAGNOSTICO CONTINUO DE LA UNIDAD DE INDUCCION FORZADA DE UN MOTOR DE COMBUSTION INTERNA POR INDUCCION FORZADA (2). EL DISPOSITIVO (1) ESTA CONECTADO A SENSORES (6) Y (7) QUE MIDEN LA PRESION DE ENTRADA (TIP) Y LA PRESION DE SALIDA (TOP) DEL TURBOCOMPRESOR (4) Y DETERMINA SU PROPORCION ACTUAL; ADICIONALMENTE, ESTA CONECTADO A UN DISPOSITIVO PARA LA DETERMINACION DEL CONSUMO (8) QUE CALCULA EL CONSUMO DE COMBUSTIBLE (FC) Y A UN SENSOR (3) PARA EL NUMERO DE REVOLUCIONES (NER) DEL MOTOR (2) Y DETERMINA LA PROPORCION TEORICA MINIMA SEGUN EL CONSUMO DE COMBUSTIBLE CONSEGUIDO Y EL NUMERO DE REVOLUCIONES. LA PROPORCION ACTUAL SE COMPARA ENTONCES CON LA PROPORCION MINIMA TEORICA Y, SIEMPRE QUE ESTA POR DEBAJO DE ESTA PROPORCION, SE GENERA UNA SEÑAL DE ALARMA A TRAVES DE UN DISPOSITIVO ADECUADO (13).
