| 摘要 | In a method for operating an internal combustion engine in which fuel arrives in at least one combustion chamber via at least one injector configured as an electromagnetic actuating device, an opening delay time of the injector (18) is ascertained by varying a control duration of the injector and analyzing a characteristic curve of an electrical operating variable of the injector that characterizes a movement of a valve element of the injector. | ||

| 主权项 | 1. A method for operating an internal combustion engine in which fuel arrives in at least one combustion chamber of the engine via at least one injector configured as an electromagnetic actuating device, the method comprising: analyzing, for different control durations of the injector, an electrical operating variable of the injector characterizing a closing of a valve element of the injector; determining the shortest control duration of the injector in which a closing of the valve element can be detected; and determining the opening delay time of the injector based on the determined shortest control duration of the injector. | ||
