Abstract
LA PRESENTE INVENCION PROPORCIONA UN SISTEMA ELECTRONICO (1) PARA CONTROLAR LA PRESION DE INYECCION DE UN SISTEMA DE INYECCION DE COMBUSTIBLE (4) EN EL QUE UNA BOMBA (8) SUMINISTRA COMBUSTIBLE A ALTA PRESION A UN RAIL (178) QUE PRESENTA UN NUMERO DE SALIDAS (19A, 19B, 19C, 19D) QUE SE COMUNICAN CON LOS INYECTORES RESPECTIVOS (21A, 21B, 21C, 21D). EL SISTEMA DE INYECCION (4) PRESENTA UN REGULADOR DE PRESION (24) QUE ESTA INTERPUESTO ENTRE LA SALIDA (8A) DE LA BOMBA (8) Y LA ENTRADA (17A) DEL RAIL (17), Y CONTROLADO POR UNA SEÑAL DE ARRASTRE (U(Z)) GENERADA POR UN CIRCUITO REGULADOR (50); AL CIRCUITO REGULADOR (50) SE LE SUMINISTRA UN SEÑAL DE ERROR DIGITAL (ERR(Z)) QUE REPRESENTA LA DIFERENCIA ENTRE UNA SEÑAL (PMIS(Z)) GENERADA POR UN SENSOR DE PRESION (38) EN EL RAIL Y UNA SEÑAL (PRIF(Z)) QUE REPRESENTA LA PRESION DE REFERENCIA OPTIMA; Y EL CIRCUITO REGULADOR (50) PRESENTA UNA FUNCION DE TRANSFERENCIA (R(Z) DEL TIPO (1), DONDE "A" Y KC SON COEFICIENTES NUMERICOS CALCULADOS, Y Z ES UNA VARIABLE DIGITAL.
