| description | PROBLEM TO BE SOLVED: To secure desired fuel injection quantity in an internal combustion engine. SOLUTION: In an injection control device driving an injector opened by discharge of a capacitor and injecting fuel to the internal combustion engine, time Tb from discharge start time of the capacitor (time 0) till current Ip sufficient to open the injector flows in the injector is measured, and process to secure appropriate fuel injection quantity according to time difference between the time TB and theoretical time Ta is executed. In an embodiment, correction to retard or advance time Te to open the injector is done. Also, correction to retard or advance discharge start timing of the capacitor is done. Furthermore, charge voltage of the capacitor is increased or decreased. Fuel injection quantity to the internal combustion engine is increased or decreased by such processing.
