Production testing of injectors

x-line is used for the automation of test sequences for injectors of Common Rail injection systems.

The following tasks had to be performed amongst others for the automation of these test stands:

  • Concept creation and realization of electrical peripherals
  • Automation of the testing procedure
  • Recording of the relevant measuring values per injection process, mainly injection pressure, injected quantity, injector current
  • Calculation of the parameters necessary for the valuation, primarily start of injection, end of injection, maximum injection pressure
  • Visualization of start of injection, end of injection and injection quantity according to duration of injection
  • OK/ NOK valuation of the tested injectors via injection quantity, specified time of the injection and pressure-time graph
  • Statistics, documentation and archiving of the testing results incl. connection to network
