PURPOSE:To continuously perform the precise injection of fuel and to eliminate the nonuniformity of mixed gas to improve the response of an engine by providing an arithmetic circuit for computing required fuel and a valve position sensor for feeding back the position of the valve body of a fuel injection valve. CONSTITUTION:The basis amount of fuel is computed through the arithmetic part 15 of a control device 6 according to the signal of an air volume sensor 1, and is corrected by various parameters from intake air temperature sensors 7- 10. An actuator 3 is driven by a comparison amplifier 17 such that the result of said operation and the signal of the valve position sensor 14 of a fuel injection valve 2 coinside with each other, so that fuel is continuously injected. In this way, the mixing nonuniformity of air and fuel is eliminated, allowing the response to be improved. |
