PURPOSE: A device for controlling fuel injection pressure is provided for a stable fuel injection and reducing noise by improving engine performance. CONSTITUTION: An injection pressure sensor(7) is installed in a fuel pipe(6) connected with a holder(5) of an injector(1). A pressure sensor(7') is installed at a nozzle end(9) of a valve body(3). An ECU(8) receives an electric signal from the injection pressure sensor(7) and the pressure sensor(7'), and controls air injection of the injector and fuel injection pressure.
