PROBLEM TO BE SOLVED: To provide a fuel injection control device of an engine which can supply a desired amount of fuel satisfying an increase amount of a required output to the engine by injecting a fuel injection amount in an exhaust stoke and an additional fuel injection amount in an intake stroke to the intake stroke in a lump when the increase amount of the required output is smaller than a prescribed value.SOLUTION: An ECU 100 comprises a fuel injection control part 101 which performs control for injecting a fuel injection amount in an exhaust stroke and an additional fuel injection amount in an intake stroke to the intake stroke in a lump when an increase amount of a required output is smaller than a prescribed value. Furthermore, when the fuel injection control part 101 detects that the increase amount of the required output is smaller than the prescribed value before starting fuel injection in the exhaust stroke, the fuel injection control part prohibits the fuel injection in the exhaust stroke, and switches it to fuel injection in the intake stroke.SELECTED DRAWING: Figure 1 |
