<p><P>PROBLEM TO BE SOLVED: To provide a fuel injection control device of an internal combustion engine capable of stably changing an engine torque to the required value irrespective of an opened/closed state of an exhaust throttle valve by suppressing that the transition of the engine torque becomes different depending on the opening/closing state of the exhaust throttle valve. <P>SOLUTION: At the time of a transient operation in acceleration and deceleration of a vehicle, a fuel injection amount is once changed to a transient target value in starting of the transient operation, and after that, the fuel injection amount is gradually changed from the transient target value to the final target value. When the exhaust throttle valve 18 is in a valve closed state, the transient target value is set to be a larger value compared to the time when the exhaust throttle valve 18 is in a valve-opened state. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
