Method for determining the absolute fuel injection quantity of the injectors (31) of an internal combustion engine with a cylinder number nz, wherein the average absolute injection quantity minj of the injectors (31) is determined on the basis of measurement data acquired during a run-up test in which all the cylinders of the engine are active and a predetermined engine-specific factor f(nz), which is proportional to the moment of inertia of the engine when all the cylinders are active, and wherein the measurement data are essentially suitable for describing the time profile of the engine speed n(t) during the run-up test, in particular a maximum achieved engine speed nmax, a first rate of change a1 of the engine speed during the running up with the injection system active, a second rate of change a2 of the engine speed with the injection system inactive and an idling speed nidle of the engine. |
