A device for testing an assembly wrench has a tool holder, and a drive element includes a fixing device which is configured to fix the tool holder. A receiving device is configured to receive and fix the drive element and may be pivoted over an arc, and at least two stops are disposed along the arc and are configured to arrest the receiving device in one defined position at a time.

Device and method for checking an assembly wrench

A holding device for a fuel injector has a mounting device to accommodate the fuel injector, and a fixing device which has a first part and a second part, which are supported in a guidance in a displaceable manner with respect to the mounting device. The second part is fixable on the guidance and between the first part and the second part of the fixing device an elastic element is situated in such a way that it is in a position to press the first part of the fixing device against a fuel injector situated in the mounting device, in order to fix it in the holding device. Also described is a clamping device for fuel injectors having at least one holding device, which is fastened elastically to the clamping device.

Holding device for a fuel injector

A method for selecting a procedure for determining the injection time of individual injection operations of a fuel injector, which may be supplied with pressurized fuel via a feed line, includes activating the fuel injector using various known activation durations in the vicinity of a predefined operating point of the fuel injector; detecting the pressure curve over time in the feed line for a number of injection operations; evaluating the detected pressure curves over time using at least two different procedures for determining the injection time from the particular pressure curve; determining the correlation between the determined injection times and the particular activation period; selecting the procedure with the highest correlation.
