PURPOSE:To prevent the reduction of the idle revolving number by a method wherein the field current of a generator is monitored to increase the opening degree of a throttle valve by a constant amount when the time of duration of the current has exceeded a given value. CONSTITUTION:When a switch S1 is closed and an electric load is connected to a battery 1, the excisting current is flowed through a field coil 3F and the alternating current generator 3 continues to generate electricity. At this time, the output of an integrator 7 increases at substantially same rate, therefore, it energizes a motor driving circuit 16 to increase the opening degree of the throttle valve 18 by a constant amount. Thus, the reduction or the fluctuation of the idle revolving number of the engine may be prevented effectively. |
