PURPOSE:To prevent an influence on a fuel injection quantity even when refer ence pressure or the pressure in an intake pipe changes, when a pressure regula tor is arranged on the inside or the periphery of a fuel tank so as to determine the reference pressure as the pressure around there. CONSTITUTION:The fuel accumulated in a fuel tank 1 is pumped up by a fuel pump 2, and is pressure-fed to an injector 4. The pressure of the fuel at this time is maintained at a fixed level in relation to the pressure in the fuel tank l, by a pressure regulator 3. The amount of fuel injected from the injector 4 into an engine 18 is controlled by an ECU 9. The fuel injection level fed to the engine is corrected by the ECU 9 based on the detection results by a pressure sensor 19 for the inside of intake pipe and a pressure sensor 28 for the inside of tank. |
