Abstract
In some embodiments, a method includes: setting an actuation time based on a predefined injection quantity; detecting a duration of a resulting closing process; calculating an injection quantity based on the time and the duration; determining the difference of the injection quantity and the predefined quantity; and determining a corrected value of the actuation time based on the difference; and using the corrected value to control further actuation of the fuel injector. The injection quantities and the actuation time are on a characteristic diagram of the relationship between the actuation time, the duration of the closing process, and the injection quantity.
