4) In addition to cleaning the fuel injection nozzle, ultrasonic device can also clean fuel pump, spark plug,
and other small size parts, but pay attention to the selection of appropriate cleaning agent.
Ultrasonic Cleaning
Injector Cleaner takes advantage of the penetrability and cavitation impact wave caused by ultrasonic wave
traveling through the medium to provide powerful cleaning on objects with complex shapes, cavities and pores,
so that the stubborn carbon deposits can be removed from the injectors.
Procedures
1) Place the injector/pump which has gone through surface cleaning in the launder.
2) Add enough injector detergent into ultrasonic cleaner so that the liquid level is about 20mm above the
needle valve of injectors / whole pump.
3) Plug the pulse signal wire to injector / pump respectively.
4) Select ultrasonic cleaning function and then set the time.
5) Press ENTER key to run.
6) When the time is up, it will stop automatically as the beeper rings.
7) Take the injector / pump out of the launder and wipe them with a dry soft cloth. Get ready for next
operation.
Note:
Do not let the ultrasonic cleaning running as ultrasonic basin without injector cleaning detergent.
Otherwise damage may be incurred.
Do not let the pulse signal cables or plug dip in the injector’s body into the detergent.
Uniformity/Sprayability Test
Uniformity test is to find out the difference of the injectors injecting at the same working condition. This test can
indicate the comprehensive influences on the injector caused by electrical nature, bore variation and clogging.
Spray ability test is to inspect the spraying performance by observing the injectors.
Installing and testing procedures for injectors
1) Choose a proper adaptor according to the injector type and mount it to the fuel distributor.
2) Install the injectors in forward direction (Apply a little lubricating grease on the O-ring.)
3) Install the fuel distributor with injector onto the plate of the test tube.
4) Connect the injector pulse signal wire.
5) Before doing this test, press DRAIN icon to drain the test liquid from the measuring cup if there is any.
6) Select Uniformity/Sprayability test function, set corresponding parameters (consult the appendix for
pressure setting, consult vehicle manuals for other parameters as needed), and then press ENTER key to
start the test.
7) When the test is completed, the equipment will auto stop with the ring of the buzzer.
Note:
a)
While testing, it can drain fuel by pressing DRAIN icon. At default, solenoid valve is set at the
