Abstract

EL METODO PERMITE LA DETECCION E INDICACION DE ANOMALIAS EN LA OPERACION DEL SISTEMA DE IGNICION (1) DE UNA MAQUINA DE COMBUSTION INTERNA QUE INCLUYE UNA PLURALIDAD DE BUJIAS DE ENCENDIDO (SP) CADA UNA DE LAS CUALES RECIBE UNA PULSACION PERIODICA DE ALTO VOLTAJE (V) QUE SALE POR UN GENERADOR DE ALTO VOLTAJE (2) EN OPERACION. EL METODO INCLUYE LOS PASOS DE: DETECTAR LA PULSACION (V) GENERADA POR EL GENERADOR DE ALTO VOLTAJE (2); COMPARAR LOS VALORES MAXIMOS DE CADA PULSACION (V) DETECTADA CON UN PRIMER Y SEGUNDO VALORES UMBRALES (S2, S3)Y; PRODUCIR UNA SEÑAL PERCEPTIBLE CUANDO LOS VALORES MAXIMOS DE LAS PULSACIONES DE ALTO VOLTAJE (V) CAEN FUERA DEL INTERVALO ACEPTABLE DEFINIDO ENTRE LOS VALORES UMBRALES (S2, S3). LA INVENCION TAMBIEN EXPONE UN APARATO PARA LLEVAR A CABO ESTE METODO.
