Abstract (en)
[origin: WO2017041923A1] The invention relates to a detection method for detecting a gap size (34) of a gap (32) between an injector valve assembly (12) of an internal combustion engine and a piezo stack (14) which is designed to actuate the injector valve assembly (12), wherein a time period (∆t) which is necessary for frictional engagement to occur between the injector valve assembly (12) and the piezo stack (14) to occur is determined, and the gap size (34) of the gap (32) is then determined from this time period (∆t). Furthermore, the invention relates to an actuation method for actuating an actuator unit (22) in the piezo stack (14) actuator unit in which, the detection method is carried out.
