Abstract
An internal combustion engine has at least one injection valve for delivering fluid, which has an electromagnetic actuator. A final stage unit is designed for creating a current profile for triggering the electromagnetic actuator with at least one given profile parameter (PP). Upon achieving magnetic saturation of a magnetic circuit of the electromagnetic actuator an assigned saturation current (I_sat_mes) is determined and at least one profile parameter (PP) is adjusted depending on the saturation current (I_sat_mes) thus determined and a given reference saturation current.
