ABSTRACT:
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.
