PROBLEM TO BE SOLVED: To provide a fuel injection control device of an engine for improving calculation accuracy of a fuel injection amount even when an air screw has been adjusted.SOLUTION: A fuel injection control device 12 of an engine 10 comprises: a bypass passage 36 for connecting an upstream side and a downstream side of a throttle valve 34 of an intake pipe 22; and an air screw 38 for opening/closing the bypass passage 36. A throttle opening correction value &Dgr;THAS is calculated by detecting an adjustment amount of the air screw 38, and a throttle opening detected by a throttle opening sensor 44 is corrected using the calculated throttle opening correction value &Dgr;THAS, so as to calculate a basic injection amount TIMB. |
