Project Description

NT800 CAT HEUI test bench

HEUI/CRI-NT800 is high pressure common rail injector and middle pressure combination test bench, which is originated by our company, Computer automatically test many types of Bosch Denso Delphi and Siemens’s solenoid valve and piezo injector, also can test  many types of CAT  HEUI injectors.

Measuring the injected fuel quantity & return volume under sealing performance, idling , pre-injection and middle-speed,full-loaded, and so on status.

User can add , edit and print the data by themselves.

Equipped with high precision flow sensor to confirm the testing precision.

Injector testing

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

6.Test piezo injectors of different models automatically

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

8.HEUI/CRI-NT800 is high pressure common rail injector and middle pressure combination test bench, which is originated by our company, can test

CAT 3126

  • CAT 3408
  • CAT C7/C9
  • Ford PowerStroke 6.0L


  • Equip industrial air conditioner to ensurethe oil temperatureat 40±2 degree
  • Equip original Bosch common rail system, rail pressure is controlled by DRV and ZME at ±0.5Mpa.
  • Equipped with original Germany KOBOLD flow sensor to make sure the testing precision.
  • Equip original Bosch CP1 pump.
  • Compact universal stand,could test solenoid valve injector or electric piezo injector.
  • Normal rail pressure 0-1800bar to make sure the testing precision (optional: rail pressure 0-2500bar)
  • For compressor cooling system, normally we use compressor made in China.  You can also choose SC15CLseries compressorprovided by Danfoss company, it comply with EU EC842/ 2006 fluorine gas law and the EU 2006/40/EC Directive (optional)

System advantage.

1.Full automatic operation with Windows XP system.

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

3.Inset test plan same as original Bosch test bench, test accuracy of our machine can be compared with Bosch bench.

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

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

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.
