摘要： An improved fuel injection control apparatus, in which a reference pressure is provided to a pressure regulator, for simplifying the fuel supply system by preventing the fuel quantity injected from injection valves into an engine from being influenced by variations in the air intake pressure. A pressure regulating device disposed in a fuel supply pipe between a fuel pump and the fuel injection valve regulates the pressure of fuel supplied from the fuel pump to the fuel injection valve so that the pressure is proportional to the predetermined pressure, without returning fuel from the injection valve to the fuel tank. An intake pressure detecting device detects the pressure in the intake pipe, and a fuel injection quantity correcting device corrects the fuel injection quantity according to deviations of the fuel pressure regulated by the pressure regulating device from a proper value due to the differential pressure between the pre-determined pressure of the pressure regulating means and the intake pressure. Accordingly, he fuel injection quantity injected from the injection valve is corrected based on the operating condition of the engine due to the variation of the intake pressure. As a result, the fuel supply system is simplified.
