POWERJET 260 PRO Injector Cleaner & Tester
V.
Operation
5.1
Resistance Test
1)
Connect one end of the resistance measurement line to the interface on the right side of the device, and the other
end to the two electrodes of the fuel injector.
2)
Start the machine, and press the
key. The resistance value will be displayed on the screen.
3)
If needed, measure several times to confirm the measured value.
4)
After the measurement is completed, remove the fuel injector and the resistance measurement line.
5.2
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
RUN
key to start the procedure.
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:
1)
It is strictly forbidden to open the ultrasonic system under the circumstances that cleaning agent has not been added into
the ultrasonic cleaning pool. Otherwise, the ultrasonic equipment may be damaged easily.
2)
It is strictly prohibited to immerse the pulse signal line connector along with the injector into the ultrasonic pool for
cleaning. Otherwise, the pulse signal line connector can be damaged easily.
5.3
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 separator.
2)
Install the injectors in forward direction (Apply a little lubricating grease on the O-ring.)
3)
Install the fuel separator 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 RUN 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 closed state.
Uniformity test can be done at this state. When DRAIN icon is pressed, solenoid valve will drain fuel.
b)
The system pressure can be adjusted by pr or – at testing.
c)
During operating, the user can select parameter, such as RPM or PW, and then press
or
key to achieve the
status of the simulation.
