1. A device for controlling an amount of fuel provided to an internal combustion engine having operating characteristics, the amount of fuel being controlled as a function of the operating characteristics, the device comprising:

  • first means for receiving at least one first input signal indicative of an operating characteristic of the internal combustion engine;

    second means for receiving a first temperature signal indicative of an intake air temperature of the internal combustion engine;

    third means for receiving a second temperature signal indicative of an internal temperature of the internal combustion engine;

    first means for generating a first output signal as a function of the first temperature signal;

    second means for generating a second output signal as a function of the second temperature signal;

    third means for generating a first weighting factor as a function of the at least one first input signal;

    fourth means for generating a second weighting factor separately from the first weighting factor, as a function of the at least one first input signal;

    first means for weighting the first output signal with the first weighting factor;

    second means for weighting the second output signal with the second weighting factor;

    means for determining a correction factor as a function of the weighted first and second output signals; and

    means for correction factor correcting a load signal of the internal combustion engine as a function of the correction factor.
