Abstract
A method for selecting a procedure for determining the injection time of individual injection operations of a fuel injector, which may be supplied with pressurized fuel via a feed line, includes activating the fuel injector using various known activation durations in the vicinity of a predefined operating point of the fuel injector; detecting the pressure curve over time in the feed line for a number of injection operations; evaluating the detected pressure curves over time using at least two different procedures for determining the injection time from the particular pressure curve; determining the correlation between the determined injection times and the particular activation period; selecting the procedure with the highest correlation.
