Abstract (en)

[origin: WO2011012518A1] The invention relates to a method for operating a solenoid valve (10), particularly an injection valve of a fuel injection system, wherein the solenoid valve (10) comprises a valve element having a valve needle (20) and an armature (14) displaceable by means of an electromagnet (13), wherein an opening motion of the armature (14) is limited by a lift stop (18), comprising the following steps: (a) determining an actuation start of the electromagnet (13); (b) determining an end of a motion (52) (impact information) of the valve element at the end of the opening motion; (c) determining a lift delay (32) using the determined actuation start (38), the determined end of motion (52), and a previously determined time of motion (56) of the valve element.
