PROBLEM TO BE SOLVED: To avoid that fuel supply into a cylinder is not in time at a second fuel operation.SOLUTION: An electronic control device 40 comprises a second ECU 42 employed to a bi-fuel engine which can switch a gasoline operation for injection-supplying gasoline into an intake passage by a gasoline injection valve 17, and a CNG operation for injection-supplying CNG into the intake passage by a CNG injection valve 31, converting a gasoline injection signal G into a CNG injection signal C at the CNG operation, and outputting it. In an engine operation state that the gasoline injection signal G is outputted in a suction stroke of an objective cylinder at the CNG operation, the second ECU 42 converts the gasoline injection signal G which is outputted with the other cylinder in the suction stroke as an object when the objective cylinder is in an exhaust stroke into the CNG injection signal C, and outputs it to the CNG injection valve 31 of the objective cylinder.SELECTED DRAWING: Figure 1 |
