Abstract
The procedure is used for the operation of an internal combustion engine () with several cylinders () into each of which fuel is injected. For a current operating point (), the current correction factor (K) for the injection into one of the cylinders () is determined. Using the current correction factor (K) at least some of the grid correction factors (K) which are stored in a correction factor characteristic map () for discrete operating points () of the internal combustion engine () are adapted. Here, a distance between the current operating point () and the discrete operating point of the grid correction factor (K) currently to be adapted is taken into account during the adaptation of the grid correction factors (K). Using updated grid correction factors (K) which are stored following adaptation in the correction factor characteristic map (), an updated correction factor (K) is determined for the current operating point () and used for the injection.
