Abstract
UN DISPOSITIVO DE CONTROL EN EL QUE UN DETECTOR DE OXIGENO LINEAL (20) DISPUESTO SOBRE UN TUBO DE ESCAPE DE GASES (5) DE UN MOTOR DE COMBUSTION INTERNA (2) EN LA PARTE DE ARRIBA DE UN CONVERTIDOR CATALITICO (8) GENERA UNA SEÑAL SUMINISTRADA A UN CIRCUITO DE CONVERSION QUE GENERA EN SU SALIDA UN PARAMETRO MEDIDO ( LA M) QUE REPRESENTA LA RELACION DE AIRE Y COMBUSTIBLE DE LA MEZCLA SUMINISTRADA AL MOTOR (2). EL PARAMETRO MEDIDO ( LA M) SE COMPARA CON UN PARAMETRO DE REFERENCIA ( LA O) PARA CALCULAR ASI UN PARAMETRO DE ERROR QUE SE UTILIZA, SEGUN UN METODO OPERATIVO, PARA GENERAR, CUANDO SEA NECESARIO, UNA SEÑAL FICTICIA BIESTABLE VARIABLE ENTRE UN VALOR DE SATURACION POSITIVO (P1) Y UN VALOR DE SATURACION NEGATIVO (-P1) PARA MODELAR ASI LA SALIDA DE UN DETECTOR DE OXIGENO DEL TIPO ON/OFF. LA SEÑAL FICTICIA TAMBIEN SE PROCESA PARA CALCULAR ASI UN PARAMETRO DE CORRECCION (KO2) DISEÑADO PARA SU USO EN LA CORRECCION DE UN VALOR TEORICO (QB) DE UNA CANTIDAD DE COMBUSTIBLE CALCULADA (40), OBTENIENDO UNA CANTIDAD DE COMBUSTIBLE CORREGIDA (QBT) PARA UN SISTEMA DE INYECCION (10) DEL MOTOR.
