Project Description

Common rail test bench

JYHY DIESEL gives Sales and Service support for diesel engine parts, like Bosch, Denso, Delphi, Cummins, CAT etc. are in our scope of supply.Our main products are injector valve, solenoid, nozzle, gasket kits, common rail injector, injection pump are also available.

We can provide complete solutions for diesel parts testing also, test bench, test tools etc.


  1. Application: Bosch,Delphi,Denso,Siemens common rail injector and pump.
  2. Pump test: measure feeding and return volume,pump chamber pressure,feeding pressure,check sealing performance, and functions of ZME valve.
  3. Injector test: measure the injected fuel quantity & return volume under full-loaded, idling, pre-injection and Emission status.
  4. Check the sealing performance of the injector.
  5. Check the solenoid valve.
  6. Clean the injector and pump before testing.
  7. Clean the ZME separately.
  8. Testing 6 oil injectors in one setup.
  9. User can add and edit the data by themselves.
  10. Save and print the testing results & customer information.
  11. Support software upgrading.
