Abstract

SISTEMA ELECTRONICO (1) PARA CALCULAR EL TIEMPO DE INYECCION EN EL QUE UNA UNIDAD ELECTRONICA CON MICROPROCESADOR (7) RECIBE COMO ENTRADA UNA MULTIPLICIDAD DE SEÑALES (N, TH20, PFARF, TARIA) MEDIDOS EN EL MOTOR Y UNA SEÑAL PROPORCIONAL A LA CARGA DEL MOTOR, POR EJEMPLO UNA SEÑAL (P) GENERADA POR UN DETECTOR DE PRESION (36) DISPUESTO EN EL COLECTOR DE ADMISION (32) DEL MOTOR (4). LA UNIDAD ELECTRONICA (7) COMPRENDE UN CIRCUITO (47) PARA COMPENSAR LOS TIEMPOS DE RETARDO DEBIDOS A LA INERCIA DE RESPUESTA DEL DETECTOR DE CARGA DEL MOTOR (36), EL REACONDICIONAMIENTO (FILTRADO, CONVERSION Y PROCESAMIENTO) DE LA SEÑAL DE CARGA Y LA ACTUACION FISICA DE LA INYECCION. LA UNIDAD ELECTRONICA (7) TAMBIEN COMPRENDE UN CIRCUITO (57) PARA LA COMPENSACION DINAMICA DEL EFECTO "FILM"FLUIDO".
