Abstract
In a method of controlling an internal combustion engine having a common rail fuel injection system including individual fuel storage chambers, wherein the pressure pattern of the fuel supplied to each injector can be determined and actual and virtual fuel injection ends and fuel injection begins are determined, the deviations from the desired fuel injection ends and from the fuel injection begins are calculated and the injectors are evaluated on the basis of the deviations and further control of the internal combustion engine is based on an evaluation of the fuel injectors.
