PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of surely preventing a fixing trouble of a fuel injection valve with fuel having a lower frequency of use by adequately executing fuel injection in an internal combustion engine including the fuel injection valve responding to two types of fuel.SOLUTION: In the case that a CNG operation mode using a second fuel injection valve 5 continues from a starting time for an engine 1, when fuel-cut operation executing conditions are established, fuel injection changeover (gasoline injection by a first fuel injection valve 4) is executed and then fuel-cut operation is started. Namely, in the case that the CNG operation mode continues, each time the fuel-cut operation executing conditions are established, the gasoline injection by the first fuel injection valve 4 is executed to prevent a fixing trouble of the first fuel injection valve 4. |
