The invention relates to a method for adjusting an injection behavior of injectors in an internal combustion engine, comprising the following steps: switching off an injector; detecting a crank angle signal of the internal combustion engine; transforming the crank angle signal into the frequency range by means of a discrete Fourier transformation; detecting and storing aquantity of the harmonic of the 0.5th order of the Fourier transform of the crank angle signal, and assigning the quantity to the switched-off injector; switching on the switched-off injector; performing the previous steps sequentially for all injectors of the internal combustion engine; forming an average value of the stored quantities with respect to all injectors, and correcting thecontrol of the injectors using a deviation from the average value of a quantity associated with an injector that is to be corrected. |
