    • A common rail fuel injection device for ensuring the main injection start timing by correcting a pulse start time of a main injection command pulse, in accordance with the length of an interval between the main injection and a pilot injection. The recovery degree of current energy for driving an injector varies in accordance with the length of the interval Tint from a pilot injection end (T4) to an main injection start time (T6), and this variation affects the main injection start time. By taking a longer value for an injector drive delay time (Td) as the length of the interval Tint is shorter, a pulse start time (T5) of a main injection command pulse CPm for performing the main injection is corrected as a more advanced timing, and hence the fuel injection for the main injection can be performed at a prescribed injection start timing.

    • A fuel injection control device includes an exhaust purification device for purifying an exhaust gas by catalytic action, an exhaust gas-temperature detection unit for detecting exhaust gas temperature, and a determination unit for determining the amount of the basic fuel injection and basic fuel injection timing from the operational status of a combustion engine, and a control unit for controlling the amount of the fuel injection and fuel injection timing. The control unit retards the fuel injection timing from the basic fuel injection timing when the exhaust gas temperature is lower than the temperature required for the catalytic activation of the exhaust purification device. The control unit also increases the amount of the fuel injection compared to the amount of the basic fuel injection to compensate for the loss of the torque output caused by the retarded fuel injection timing.
