Abstract (en)

[origin: WO2022090395A1] The invention relates to a method for determining an opening time of an injector having a solenoid valve. The method comprises: determining a time of contact of the armature, at which an armature of a solenoid valve comes into contact with a valve needle of the solenoid valve; determining an opening delay time of the injector, which corresponds to a time span between the time of contact of the armature and an opening time of the solenoid valve; and determining an opening time of the injector based on the time of contact of the armature and the opening delay time.
