Abstract
An engine operational condition detector detects a mode among several modes, such as an idling state, a steady state and an accelerating state, where a signal is utilized for selectively actuating one of several integrators, each of which has a predetermined time-constant. One of the integrators, when actuated, integrates an output signal of a P-I controller of a closed loop fuel control system, the integrated signal being stored in a capacitor connected across the integrator. Electromagnetic valves disposed in the openings of main air-bleeds of main and slow circuits of a carburetor are energized in accordance with the output signal of each integrator while other electromagnetic valves disposed in the openings of auxiliary air-bleeds of the same are energized in dependence on the output signal of the P-I controller.
