PROBLEM TO BE SOLVED: To eliminate anxiety that there occurs the lowering of an output or the like due to the insufficiency of a fuel amount in a cylinder when (immediately after switching, particularly) switching between liquid fuel and gas fuel is performed, in a bi-fuel internal combustion engine.SOLUTION: A fuel supply device (50) comprises a switch command output part (532), a switch execution part (533) and a fuel injection amount correcting part (534). The switch command output part outputs a switch command signal for switching between the injection of the liquid and the injection of the gas fuel. The switch execution part switches between the injection of the liquid fuel and the injection of the gas fuel on the basis of the output of the switch command output part. The fuel injection amount correcting part corrects an increase amount of the fuel injection amount in the fuel injection before (typically, immediately before) being switched by the switch execution part. |
