The present invention relates to a method for determining the fuel quality in an internal combustion engine, in particular of a motor vehicle, in which method it is provided, in particular, that a two-stage zero quantity calibration is carried out, wherein, in the first stage, a test injection is carried out with an actuation duration and a first quantity correction is produced, wherein, in the second stage, two test injections are carried out with said actuation duration, the time interval between which two test injections is selected in such a way that the influence of a pressure wave which is generated by the first test injection on the second test injection is as low as possible, and a second quantity correction is produced using the two test injections, wherein the first quantity correction and the second quantity correction are compared with one another and a conclusion about the fuel quality is made from the result of the comparison. |
