摘要： In order to perform fuel injection control for a diesel engine, data read by an ignition timing data reading means is compared with a reference data to calculate an ignition timing difference. The ignition timing error is compared with a predetermined threshold value to decide whether or not the ignition timing difference exceeds the predetermined threshold value. A pilot injection timing correction data is generated in accordance with the result of the decision. The pilot injection timing control data is instructed in accordance with the pilot injection timing correction data, and pilot injection timing control is performed in accordance with the pilot injection timing control instruction. A feedback control of a signal based on an output from the ignition timing detector is used for control of a pilot injection timing, so that ignition at a desired ignition timing is performed.

摘要： A fuel injection system comprising a fuel injection pump, at least one fuel injection nozzle connected thereto, and a control device for varying the rate of injection of the system according to varying engine parameters. The control device has a variable volume chamber, the volume of which is varied by a piston located by a piezoelectric actuator. The variable volume chamber and a pumping chamber of the pump is intermittently connected by a passage which is specifically designed in such a manner that the fluid communication between the chambers, during the delivery stroke of a pump plunger, is provided only for an initial stage of the delivery stroke. A rate of injection is controlled in the initial stage to perform a pilot injection. In the subsequent stage, in which there is no need for rate-of-injection control, the variable volume chamber is isolated from the pumping chamber in order to relieve the piezoelectric actuator from an excessively high fuel pressure that would cause degradation of the piezoelectric elements.
