1. Introduction

1.1 Description

Functions:

NTS208 Common Rail Injector Test Bench is our latest independent researched special device to test the performance of high-pressure common rail injector, controlled by industrial computer, Windows7 operating system. The oil quantity is measured by sensor and displayed on computer screen (Electronic fuel delivery system). All data can be searched and saved. It adopts BOSCH (DENSO) original common rail pump to provide 0-2500 bar for rail pressure .The rail pressure can be adjusted automatically, and it also provide pressure overload protect. It can test common rail injector of BOSCH, DELPHI, DENSO and SIEMENS. It adopts the advanced technology, steady performance, precise measurement and convenient operation.

1.2 System Application:

l 1.21 Common rail Injectors

1. Fully automatic detection of electromagnetic injectors of various brands add models such as BOSCH,DENSO DELPHI SIEMENS,etc....

2. Coding of injector, generation of new code:

3. Test the Leakage performance of common rail injector.

4. Injection oil quantity and back oil quantity(VL( full load )TL (Middle speed Emissions) LL( Idling) VE ( Pre-injection)

5. Solenoid valve inductance, capacitance detection.

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

7. Detect the response time BIP of the injector.（accessories optional)

8. Detect the dynamic stroke of the injector AHE. (accessories optional）

l 1.22 Characteristic

1. Controlled by the computer in real time, Windows7 operating system, touch screen operation.

2. Oil quantity is measured by sensor and displayed on 17 inches LCD screen.

3. Using the original BOSCH high pressure common rail oil pump to provide 

0 ~ 2500 bar rail pressure.

4. The injector’s injection times can be set freely;

5. Rail pressure can be tested in real time.

6. Provide pressure overload protection.

7. Pulse width and frequency of the injector drive singal can be adjusted.

8. Injection time can be settled.

9. Protection function of short-circuit.

10. Precise measurement, easy operation, low noise and energy saving.

l 1.23 System advantage:

1. Full automatic operation with Windows7 system.

2. Original Bosch testing database: current curve can be set. Test accuracy similar with world leading test bench.

3. It include more than 7000 types testing data of BOSCH, DENSO. DELPHI SIEMENS injectors and pumps. The database can be edited, modified and regularly updated.

4. Self-protection under overheat, oil mist , over pressure and low oil level.

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

6. Include CHINESE ENGLISH, SPANISH, RUSSIA language etc.. which are proper for global using.
