摘要： A method for joining studs to workpieces, in particular for the purpose of stud welding, comprising the steps of acquiring a distinguishing dimension of a stud to be joined by the application of a sensing element to the stud and through measurement of a travel distance of the sensing element as it is applied to the stud; and then joining the stud to a workpiece, if the dimension of the stud is within an allowable tolerance range, and the allowable tolerance range is adapted in dependence on the travel distance of the sensing element measured during a preceding method step.

摘要： A method for learning and determining a minimum injector-specific electric actuation duration for at least one fuel injector of an internal combustion engine of a motor vehicle. Starting with a predefined electric actuation duration which definitely does not result in an injection, the electric actuation duration is gradually increased in each engine stop and/or in each engine start in successive engine stops and/or in successive engine starts of the internal combustion engine up to an actuation duration in which an injection with a combustion occurs, and then this actuation duration may be determined as the minimum electric actuation duration. The invention also relates to a corresponding device.

摘要： In an internal combustion engine, fuel is injected directly into a combustion chamber by an injector that has a piezoactuator. An electrical charge conveyed to and/or removed from the piezoactuator is ascertained by a method that is calibrated at least once during an operating time span of the internal combustion engine. To allow the calibration to be carried out or performed as often as possible, the method for ascertaining the electrical charge transferred to and/or removed from the piezoactuator may be calibrated during at least one triggering off-time (dtK) of the piezoactuator while the internal combustion engine is operating.

摘要： A method for operating a fuel injection system for an internal combustion engine is provided, in which monitoring is performed as to whether an overlapping occurs between a time interval in which one piezoelectric element for injecting fuel into a cylinder is to be charged or discharged, and a time interval in which a different piezoelectric element for injecting fuel into a different cylinder is to be charged or discharged. The monitoring is performed as to whether, in the context of a lower-priority injection, the charging or discharging occurs within a predefined time interval around the point in time of a charging or discharging of a higher-priority injection, the spacings of time-related charging and/or discharging edges (edge overlaps) being determined during operation of the fuel injection system, and the magnitude of the shift and/or shortening of the lower-priority injections with respect to the higher-priority injections being determined therefrom.
