  • Fuel injection apparatus and method of manufacturing same
    Patent number: 7779814
    Abstract: A fuel injection apparatus includes an accumulator, an injector, a fuel supplier supplying fuel to the accumulator, and a controller controlling a fuel supply rate of the fuel supplier through manipulation of a manipulated variable. The controller is configured to set a target fuel supply rate, determine a base target value of the manipulated variable as a first function of the target fuel supply rate, determine a correction value as a second function of the target fuel supply rate, correct the base target value of the manipulated variable using the correction value to obtain a final target value of the manipulated variable, and manipulate the manipulated variable to have the final target value, thereby bringing the fuel supply rate of the fuel supplier into agreement with the target fuel supply rate. The first and second functions are predefined prior to the installation of the fuel injection apparatus to an engine.
