Abstract

PURPOSE:To heighten the accuracy of control of injected fuel quantity, by compensating the injected fuel quantity to be equal to a command, depending on the temperature of the fuel, and by placing a fuel control member in a position corresponding to the command, depending on the rotational frequency. CONSTITUTION:An operating condition detection unit 1 comprising an accelerator displacement detector 1a, a rotational frequency detector 1b, a fuel temperature detector 1e and so forth is provided. The quantity of injected fuel is compensated to be equal to a command, on the basis of the detection signal of the fuel temperature detector 1e. The detection signals of the accelerator displacement detector 1a and the rotational frequency detector 1b are applied to an electric control circuit 2 including a microcomputer 2a, to calculate the position of a fuel control member 4, which corresponds to the fuel injection quantity command. An electromagnetic actuator 3 is driven depending on the difference between the position of the fuel control member 4 and the detected value of an actual position detector 7, to regulate the fuel control member. As a result, the accuracy of control of the quantity of injected fuel is heightened in any of slow operation and load fluctuation.
