How to use it ?

The common rail injector connected directly or mount holder to ordinary hand-pressure high-pressure pipeline verifier.

Injector brand select the appropriate plug according to the injector harness correctly connected.

According injector brand, select the corresponding drive mode, this time to hear the injector solenoid valve armature sucked up "pop, pop" sound.

By constantly under pressure checker leverage, provide a suitable injection pressure, the general pressure to take 30-40MPA best, then you can observe injector atomization.

Through an external cylinder, can Injector volume and return oil were detected.

Common detection Features



Armature stroke position detection

    Correct injector solenoid valve connected to the detector harness. Frequency adjustment to 1000, the pulse width from the minimum position slowly adjust to the position of the large observed value adjustments where, injector solenoid valve begins audible. Then turn to other injectors do comparison. If there should be a large error value is adjusted by adjusting shims.

If there injector adjustments to the maximum width, the injector solenoid valve still does not work, then you can remove the solenoid valve wiring harness connector opening detector power, the solenoid valve is energized face of metal, observe electromagnetic Is there a suction valve, such as solenoid valves exist to prove the armature suction stroke is too large (by replacing the washer stroke), as there is no proof solenoid suction is corrupted.





Pre-injection detection

       Correct injector solenoid valve connected to the detector harness. Frequency, pulse width adjustment to the minimum position. The calibration pressure hit 50MPA, run detector, this time due to the pulse width in the minimum position, injector atomization not appear, gradually increasing the pulse width to the minimum atomized atomized state, viewed from the 50MPA to 20MPA atomizer several times. Preferably one of the same model new injectors do comparison.
