ABSTRACT:
A fuel control system for a multicylinder internal combustion engine, wherein the fuel is metered by a fuel metering device having one fuel metering orifice whose degree of opening is variable depending upon the quantity of intake air and a differential pressure regulating valve for maintaining the differential pressure across the fuel metering orifice at a predetermined magnitude, and a distributor has a plurality of distribution valves equal in number to the cylinders of the engine, each distribution valve being hydraulically communicated with the fuel metering device, and a plurality of pressure equalizing valves also equal in number to the cylinders, each pressure equalizing valve being communicated with each distribution valve. The whole quantity of fuel to be supplied to the respective cylinders is precisely metered by the fuel metering device in proportion to the quantity of intake air, and the metered fuel is uniformly distributed among the fuel injection nozzles by the distributor.
