Abstract

PURPOSE: To reduce noise in idling of an engine without causing the lock of output excepting in case of idling by a method wherein a means for reducing the fuel injection factor is provided only when the engine is idling.
CONSTITUTION: Only when the engine is idling there is provided a controlling part including an integral circuit 55 and the like for reducing the fuel injection factor. When a detecting circuit 46 of idling of engine detects that the engine is idling, first of all, the stopper of a controlling device 27 of the number of rotation in idling is located and controlled so that the number of rotation in idling is designated by a differential pulse signal S15 slightly higher than that shown by the desired signal S6. After that, when an intended time passes after the idling state is detected in a circuit 46 by an integral signal S14 from the integral circuit 55, a quantity-governing soleniod tromagnetic valve 12 grows weak, throttle governing comes in effect and the fuel injection factor is lowered. Thereby, the device is put into a stable working state and mothing but noises which occur in an idling time can be reduced remarkably without lowering the output in load running of the engine.
