| description | A fuel supply apparatus for an internal combustion engine is disclosed. The fuel supply apparatus includes a fuel pump driven by the engine, a pressure accumulating device for retaining the fuel pressurized by the fuel pump, a relief device which opens when a fuel pressure in the pressure accumulating device exceeds a predetermined upper limit pressure. An injection device is connected to the pressure accumulating device and injects fuel into a combustion chamber of the engine. A fuel pressure in the pressure accumulating device is detected. A discharge amount of the fuel pump is controlled so that the detected fuel pressure coincides with a target fuel pressure. The target fuel pressure is reduced when the detected fuel pressure is equal to or greater than a predetermined fuel pressure, to suppress opening of the relief device. |
