Abstract:
A method for recognizing a state change of a fuel injector of an internal combustion engine, in which fuel from a high-pressure accumulator is injected into a combustion chamber with the aid of the fuel injector. A value that is representative of a static flow rate of fuel through the fuel injector is ascertained. A state change of the fuel injector is deduced when the representative value differs from a comparative value by more than a first threshold value.

Claim (Index 27):
The method as recited in  claim 16 , wherein the representative value is determined by ascertaining, for at least one injection operation of the fuel injector, a ratio of a pressure difference that occurs in the high-pressure accumulator due to the injection operation, to an associated time period that is characteristic for the injection operation.
