Abstract
A fuel feed system adapted to maintain at a constant value the pressure difference across a fuel measuring gate disposed in a fuel feed passage and control the area of opening of the fuel measuring gate in connection with the amount of air being sucked into an internal combustion engine so as to continuously measure the fuel, the measured fuel being concentratedly injected at a positive pressure into the suction pipe. The system comprises an accelerator pump interlocked to a throttle valve for injecting fuel at a positive pressure into the suction pipe during acceleration. The accelerator pump is fed with fuel sucked up from the return pipe of a pressure regulator which feeds the fuel measuring gate with fuel at a predetermined pressure.
