How to test a common rail Injector ?
Need two conditions:
1,Electrical pulse signal (CR-C Common Rail Injector Tester )
2, High pressure fuel (S60H Common rail diesel nozzle Injector
As Shown below picture, it's the basic method.
CR-C Common Rail Injector Tester
CR-C common rail injector tester is a easy operated tool, could do
the test with the injector hand pumps. It’s small size and light
weight, could meet the requires from repairman on the simple device
Produce Model: CR-C Common Rail Injector Tester
Testing Range: atomization, pilot, emission and full load
Test Injectors: for Boscch, Densso, Delphii common rail injectors.
Working Voltage: AC220V/AC110
Working Temperature: -30C°——70C°
Adjustable Width: 10 MS
Common rail diesel nozzle Injector tester S60H
Diesel Injector Nozzle Pop Tester fuel injector nozzle tester with
0 - 400 BAR / 0 - 6000 PSI Dual Scale Gauge BOSCH injector checker
is suitable for all common rail injector and mechanical injectors,
auxiliary products have compression release valve, it can check the
fuel injection conditions of various types of injector quickly and
easily. It also can be used with common rail injector 118 solenoid
valve tester to test various types of common rail injectors. The
injector checker equipped with two different types of tubing. You
can freely switch suitable for detecting the injector, it is a good
choice to Initial inspection injector working state.
HOW to Test
As we know driver common rail injector,not only need a tester but
also need hight pressure fuel,
so we used a manul fuel pressure pump S60H as show in follow
1, the high pressure oil common rail injector directly or into the
holder is connected to the common hand pressure calibrator.
2, according to the corresponding plug injector brand choice, will
harness and injector connected up correctly.
3, according to the fuel injector brand, drive mode selecting
corresponding, at this time can hear the injector solenoid valve
suction armature "Pa, Pa" voice.
4, by constantly under pressure calibrator lever, provide the
suitable injection pressure, the general pressure value takes
30-40MPA best, at this time can be observed on the fuel injector
5, through the external cylinder, can be detected on the injector
fuel injection quantity and oil retur
Test BOSsCH injector ,use the connector for bosch
