Abstract (en)
[origin: WO2022090397A1] The invention relates to a method for determining a closing time of a solenoid valve of an injector, wherein the closing time is determined by ascertaining a logarithmic voltage ratio between a coil voltage and a reference value for the coil voltage, the coil voltage being a voltage applied to a coil of the solenoid valve.
