Abstract (en)
[origin: WO2011000650A1] The present invention relates to a method for operating an internal combustion engine (10), wherein fuel reaches at least one combustion chamber (20) by means of at least one injection valve (18) comprising an electro-magnetic actuating device (24). By varying the control period of the injection valve (18) and analyzing a course of an electric operating variable of the injection valve (18) characterizing a movement of a valve element (28) of the injection valve (18), the opening delay time of the injection valve (18) is determined.
