摘要： In an apparatus for controlling the fuel injection advance angle of a fuel injection pump having a hydraulic type timer with a solenoid valve, the apparatus has a closed-loop control system in which the solenoid valve is controlled so as to be closed or opened in accordance with a first control signal produced in response to a feedback signal showing the actual injection advance angle so that the actual injection advance angle is made to coincide with a desired target injection advance angle when the feedback signal is in a predetermined condition, and the solenoid valve is controlled by a second control signal in the open-loop control mode so as to be continuously closed/opened whereby to regulate the average opening degree of the solenoid valve in order to obtain the optimum injection advance angle when the feedback signal is not in the predetermined normal condition.
