Abstract
PURPOSE: To prevent the air/fuel ratio from changing to the lean side by providing a correction device to increase the fuel when the opening of carburettor throttle valve exceeds the preset value and it is sensed by an idling revolutions control device which is to hold the idling revolutions constant.
CONSTITUTION: When the number of revolution of an engine becomes lower than the set value, the signal from a rotation sensor 18 will generate a pulse signal from a control circuit 19. An actuator 17 is put into operation by this signal to control the duty ratio. On the other hand, the output (d) of a circuit L1 to integrate the signal from the rotation sensor 18 in control circuit 19 becomes a value corresponding to the opening of a throttle valve 3g. Output (f) is given by the circuit R1 as reference signal for sensing if this value has attained a certain specified value. When the order of magnitude between two signals (d) and (f) is inverted, the correction signal (h) will permit the actuator 15 to shut an air bleed 10 to increase fuel supply from a float chamber 3a. Thus the air/fuel ratio of the mixture can be concentrated.
