ABSTRACT:
An electronic governor of a fuel supplying device for an engine is disclosed. The governor is operated to control an adjustment member for adjusting an amount of supply of fuel to the engine. In a target idling position arithmetic circuit, a primary arithmetic circuit calculates a primary target position of the adjustment member in accordance with the detected rotational speed of the engine with reference to a predetermined relation between the rotational speed of the engine and the position of the adjustment member where the supply amount of fuel is reduced as the rotational speed of the engine is increased. A first correction circuit corrects the primary target position by using a first position correction component in a fuel supply amount increasing direction, such that the detected rotational speed of the engine is coincident with a target idling rotational speed. A second correction circuit corrects the primary target position by using a second position correction component in a fuel supply amount reducing direction in such a manner as to correspond to the position of the adjustment member detected by a position detection circuit when the idling control is undergoing.
