ABSTRACT:
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.
