Further, the method includes the steps of detecting an actually measured value (Q) of a fuel injection amount of an engine (1) and an actually measured value (Ne) of a rotational speed at every predetermined time and controlling an output voltage of the power generator in accordance with a deviation value (&agr;2) between a predetermined target value (Q1) of the fuel injection amount with respect to the actually measured value of the rotational speed and the actually measured value of the fuel injection amount.

摘要： In a fuel injection apparatus 1, a fuel injection rate from which is controlled by a fuel pressure, a branch pipe 11 comprising a tubular member with the tip end closed is provided between a second pressure control valve 9 and a second pressure sensor 10. The branch pipe 11 extends in a direction along a flow direction of the fuel just before the branch pipe 11, and has a capacity not less than one fifth of that of a fuel flow path 22 between the second pressure control valve 9 and a fuel chamber 17. When a pressure difference in the pressure control valve 9 becomes larger and vibration of the fuel pressure is generated, the branch pipe 11 absorbs and reduces the vibration. As the vibration of the fuel pressure is reduced, a stable fuel injection rate is realized.
