1. A system for indicating, recording and evaluating a driving-data mode of a vehicle for fuel economy, comprising:

  • a fuel-injection amount-detecting unit for detecting a digital signal converted from an analog signal determining a fuel-injection amount;

    a maximum point-assigning unit for assigning the maximum point of the fuel-injection amount;

    an engine idle driving fuel-injection amount driving point-assigning unit for assigning a driving point having a fuel-injection amount for engine idle driving;

    a ¾

    point-assigning unit for assigning a point to be ¾

    of a distance from the driving point having the fuel-injection amount for engine idle driving to the maximum point of the fuel-injection amount;

    a ⅕

    point-assigning unit for assigning a point to be ⅕

    of the distance from the driving point having the fuel-injection amount for engine idle driving to the maximum point of the fuel-injection amount;

    a fuel-injection amount cutting point-assigning unit for assigning a point for cutting off the fuel-injection amount;

    a fuel-injection amount display-indicating unit for indicating the display of the fuel-injection amount and recording the display for a designated period;

    a fuel-injection amount graph-regulating unit for finely regulating a graph illustrating the fuel-injection amount; and

    a liquid crystal display unit for displaying obtained results, wherein variables of the assigning units are set.
