ABSTRACT:
In a fuel injection nozzle system having an injection-valve which is able to adjust the opening pressure to any value, there is provided with a device for adjusting the opening pressure of the injection-valve, a setting circuit for setting a target value for the injection-valve opening pressure in response to at least one signal indicative of the condition of engine operation, and a detecting circuit for detecting the actual value of the injection-valve opening pressure set by the device. The output signals from the detecting circuit and the setting circuit are applied to a circuit for computing the difference between the actual value and the target value and the device is operated in accordance with the signal indicative of the difference so that the actual value of the injection opening pressure is set at the target value of the injection-valve opening pressure with high accuracy.
