PROBLEM TO BE SOLVED: To provide a pressure storage type fuel injection control apparatus capable of reducing overshoot and undershoot of rail pressure regardless of a fuel temperature.SOLUTION: A pressure storage type fuel injection control apparatus includes a common rail to which a plurality of fuel injection valves are connected, a high pressure pump feeding fuel to the common rail, a flow rate control valve for controlling a flow rate of the fuel fed to the common rail, and an electronic control unit executing a drive control of the fuel injection valves and the flow rate control valve, wherein a compensation control section for delaying the timing changing a fuel injection quantity when the electronic control unit predicts that the change of the fuel injection quantity by the fuel injection valves becomes not less than a predetermined quantity. The apparatus is characterized in that the timings in which the compensation control section changes the timing changing the fuel injection quantity are different according to the fuel temperature. |
