摘要:
A fuel injection control for an internal combustion engine having electromagnetic fuel injectors determines a basic fuel injection time width of a fuel injection pulse signal applied to the electromagnetic fuel injectors in accordance with detected conditions of engine operation parameters, stores maximum fuel injection time width values predetermined in correspondence to values of a predetermined one of the engine operation parameters, reads one of the predetermined maximum fuel injection time width values corresponding to the values of the predetermined engine operation parameter and corrects the same in accordance with the values of the other engine operation parameters, and corrects the basic fuel injection time width in accordance with the corrected predetermined maximum fuel injection time width value, thereby controlling the air-fuel ratio at a desired air-fuel ratio under every operating condition of the engine, while simultaneously preventing a misoperation of continuous fuel supply from occuring in the electromagnetic fuel injectors as before.
