摘要：Disclosed is a fuel injection control apparatus wherein the quantity of fuel supplied to an internal combustion engine is derived from engine operating parameters including a voltage signal which is generated by electromagnetic induction as a function of engine speed. A fuel injection quantity calculation circuit derives the fuel quantity in accordance with the detected operating parameters of the engine. A fuel injection controller provides injection of fuel in accordance with the calculated fuel quantity when the sensor voltage is valid and provides forced fuel injection regardless of the calculated fuel quantity when the sensor voltage is invalid and the engine starter is being operated.
