Common rail injector Return flow testers

• The return flow volume is a clear indicator of the quality of a common rail injector. A defective injector has a higher or lower return flow volume than an injector that works as designed.
• Also suitable for piezo injectors, in conjunction with back pressure valve
• Testing options:
  • Identification of defective injector in the event of starting problems
  • Comparison of return flow volume of various common rail injectors
  • Determination of return flow volume
