摘要： A fuel control system for an internal combustion engine with an unbalanced sensing vane pivotally disposed in an intake pipe upstream of a throttle valve, an actuating device having a pressure chamber and a movable diaphragm coupled to the sensing vane for actuating the same in response to a pressure applied to the pressure chamber, and a conduit communicating the pressure chamber with the intake pipe between the sensing vane and the throttle valve, a pressure difference responsive valve responsive to a pressure difference across the sensing vane to compensate the pressure applied to the pressure chamber to control the pressure difference across the sensing vane at a constant value irrespective of changes in the amount of intake air, and a fuel metering valve coupled to the sensing vane to meter and distribute fuel in response to the pivotal movement of the sensing vane. The fuel control system is also provided with a solenoid valve to actuate the same in response to deviations from a given air fuel ratio, whereby the pressure difference across the sensing vane is maintained at another constant value.
