Abstract
A method for ascertaining the absolute fuel injection quantity of the injectors of an internal combustion engine including a cylinder number, the average absolute total injection quantity of the injectors being ascertained based on a run-up test in which all cylinders of the engine are active, recorded measurement data, and a predetermined engine-specific factor which is proportional to the moment of inertia of the engine when all cylinders are active, and the measurement data being essentially suited for describing the chronological progression of the engine speed during the run-up test, in particular a reached maximum engine speed, a first rate of change of the engine speed during the run-up with active injection, a second rate of change of the engine speed with inactive injection, and an idling speed of the engine.
