Abstract (en)
[origin: WO2015022058A1] The invention relates to a method for the injector-specific diagnosis of a fuel injection device (3) of an internal combustion engine (1), comprising the following steps: detecting a pressure progression (D) in an individual accumulator (7) of an injector (5) in a time-resolved manner; evaluating the detected pressure progression (D); determining if there is a fault state of the injection device (3) in the region of the injector (5) on the basis of the detected and evaluated pressure progression (D); and identifying the fault state on the basis of the detected and evaluated pressure progression (D).
