PURPOSE:To make highly accurate control achievable, by detecting a state of battery voltage from time till a continuous rating current for an injector reaches to the specified value, while compensating various quantities being dependent upon a variation in the battery voltage according to a state of electric load in the battery. CONSTITUTION:In time of engine operation, when an injection pulse signal Tp is generated out of a control processing unit 20 in a control unit via a timer part 25, an injector 1 is excited via a current-carrying ignition control part 27. If so, at this time, a pulse is generated at peak current arrival time whereby the time is stored in the timer part 25. Thereupon, battery voltage VB is found out of the continuous rating time of the injector 1 based on this arrival time, and thereby an ignition timing value to be obtained from a speed pulse signal Np5 and a suction air quantity signal Q6 and both conduction starting and finishing times all are outputted to the timer part 25 on the basis of the said continuous rating time. Then, the injector 1 is made so as to be controlled in accordance with output of this timer part 25. |
