PURPOSE:To permit the proper fuel injection in accordance with the driving state by detecting the transition state of the number of revolution of an engine and varying the fuel injection interval synchronized with the revolution of a crank shaft. CONSTITUTION:The operation state of an internal-combustion engine 2' is detected by an operation-state detecting means 50, and the specific transition state of the internal-combustion engine is discriminated by a detection means 56. When the specific transition state is detected, the injection interval is varied by a varying means 58. Thus, proper fuel injection in accordance with the operation state can be performed.
