<P>PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine which is capable of stably carrying out suction port injection after an autonomous operation without depending on a pulsation damper while employing a dual injection system. <P>SOLUTION: In the internal combustion engine 10, fuel is supplied to a fuel injection valves 11b-14b for the suction port injection through a low pressure fuel passage 30 and a low pressure fuel passage 50. High pressure fuel is supplied to fuel injection valves 11a-14a for a cylinder fuel injection through the low pressure fuel passage 30 and a high pressure fuel passage 40. An electronic controller 20 for controlling the drive of the fuel injection valves 11b-14b for the suction port injection and the fuel injection valves 11a-14a for the cylinder fuel injection corresponding to the operation condition of the internal combustion engine 10 corrects the amount of the fuel injection by the fuel injection valves 11b-14b for the suction port injection corresponding to the pressure fluctuation caused by the drive of a high pressure fuel pump 40P during engine start-up from the autonomous operation to the idling. <P>COPYRIGHT: (C)2013,JPO&INPIT |
