Abstract: PURPOSE:To aim at smooth control over engine revolution, by forming a first idling output with an engine speed and a desired engine speed at a time when an idling state elapses as long as the specified time, while controlling the engine output according to the sum total of the output value and an accelerator operating value. CONSTITUTION:Under the following conditions that a signal S3 comes into a state of being turned ON as an air conditioner 20 is operated, while output of a volume 28 detecting an accelerator operating value is zero and an engine speed N is higher than the specified engine speed Ns (about 1,500r.p.m.), a first idle condition is not materialized whereby controller output signals S4 and S5 come to OFF. Next, when the specified time elapses as coming to N<=Ns, these controller output signals S4 and S5 come to ON. If so, a time integral value of the difference between N and Ns is added to an adder 26 so that feedback control for the engine speed takes place. Then, when a accelerator pedal is operated and comes to S1not equal to 0, the output S4 turns OFF, opening a switch SW1, and the adder 26 comes to emit the sum total of the S1 and the output of an integrator 22 as driving output S2 of a throttle valve in consequence.
