PURPOSE:To enable to precisely control the injection amount of fuel, by a method wherein an error in the substantial injection amount of fuel from an injection pump to the target amount is calculated from an output of a drive condition detector, and a fuel regulating section is operated in response to the result of calculation. CONSTITUTION:The acceleration operating amount signal, an engine speed signal and a cooling water temperature signal are put out from an engine operating condition detector 1, and the output is given to an electric control circuit 2. In this circuit 2, the signal of a target injection amount of fuel in response to the amount which is to be injected into an engine 6 is calculated from the above-mentioned signals, respectively. In addition, the signal of a substantial injection amount detected by a substantial injection amount detector 7 is put into a circuit 2, a deviation signal calculated here from the input signal and the target injection amount signal is put out, to control a fuel regulating part 4 through an electromagnetic actuator 3, to get rid of the deviation. Further, a control circuit 2 has a function to increase and decrease the injection amount of fuel in response to a cooling water temperature signal, when an engine 6 is in a cool condition.
