Project Description

CR-NT915 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.


Injector test

1.Cleaning: High pressure cleaning for the impurities inside the injectors.

2.Testing the injection and return volume under VL, TL, LL, VE and VE2 status.

3.Atomization test: to judge whether the injector is blocked through the atomization effect.

4.Sealing test: check whether nozzle, nozzle cap nut and solenoid valve leaks oil.

5.Test solenoid valve injectors of different models automatically and test 6 injectors continuously.

6.Test Piezo injectors of different models automatically and test 6 injectors continuously.

7.Test Piezo injector assembly of large resistance value(>2.5 Ohm).

Pump test:

1.Automatically test injection and return volume, pump chamber pressure, feeding pressure and sealing performance for Bosch, Siemens, Denso and Delphi common rail pumps.

2.Automatically test VP37 and VE37 pump test system.

3.Automatically test EUI and EUP. The EUI additional system can test products of Bosch, CAT, Cummins,DDC,Delphi, Mercedes Benz, Volvo, Scania, Iveco etc.

4.Test special Denso HPO pumps with 8 cylinder double magnetoelectric sensor, 6 cylinder single magnetoelectric sensor or 6 cylinder Hall sensor.


  1. Air-conditioner to keep the oil temperature controlled at 40±2℃.
  2. Equipped with original Bosch common rail system. The rail pressure is controlled by DRV and ZME valve at ±0.5 Mpa.
  3. Equipped with Germany flow sensor, the flow range is 0.008-4L/Min, the test precision is 0.3%.
  4. Equipped with original Bosch CP3.3 pump.
  5. Compact universal stand can test 6 solenoid valve injectors or Piezo injectors successively one by one or continuously .
  6. The range of rail pressure is 0-2500bar with precise measurement, easy operation, low noise and energy conservation.
  7. Output power (optional): 11kw, 15kw.
  8. Lubrication oil system: ensure the stability of the tested parts.
  9. Danfoss compressor of SC15CL series which is in accordance with the European UnionEC842/2006 and European Union Directive 2006/40/EC  is equipped to the cooling system.

System advantage:

1.Full automatic operation with Windows XP system.

2.Embedded industrial computer system: high speed operation and stable performance.

3.Original Bosch test bench database to ensure the test precision.

4.Powerful database of over 1000 kinds of Bosch, Delphi, Denso and Siemens injectors and pumps.

5.Separate management of injector and pump database with memory function. The database can be edited, saved, modified and regularly updated.

6.Users can choose to test step by step or continuous test and choose to test one or six injectors at one time.

7.Users can choose to take the automatic judgment by computer or by themselves.

8.Self-protection under overheat, oil mist, overpressure and low oil level. It will be showed by the indicator lamp.

9.Support multi-language version such as Chinese, English, German, Spanish, French, Russian etc.

10.Remote control is convenient for service and software upgrade.

11.Support customized products and application.

Power supply:

We provide three types of model three-phase, 380V/50Hz, three-phase 220V/60Hz and two-phase 220V/60Hz in convenient for the different need of power supply in different countries.
