    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.

    摘要: In an idling operation controlling apparatus for performing an individual cylinder control of a multi-cylinder internal combustion engine, individual cylinder control data is corrected only during a predetermined period in accordance with a predetermined parameter relating to the state of the control of the amount of fuel injection of the internal combustion engine, in such a way that the time period required for the regulation of the injection quantity for each cylinder to reach a desired state is shortened, thus the response characteristic of the individual cylinder control system can be improved.

    摘要: An idling operation control apparatus consists of a closed-loop control system responsive to an average speed of a multi-cylinder internal combustion engine for obtaining a target idling engine speed. In the closed-loop control system, there is provided an individual cylinder control system in which a first data relating to outputs of respective cylinders of the engine is produced in response to an operation timing of the engine and the differential data showing the difference between the output of the respective cylinder and the output of a reference cylinder is calculated on the basis of the first data. A second control data relating to the fuel amount necessary for nullifying the difference indicated by the differential data is also produced in the latter system and the second data is supplied to the closed-loop control system, whereby the difference among the outputs of the cylinder is reduced.
