Note:
1) While testing, it can drain fuel by ressing DRAIN icon. At default, solenoid valve is set at the closed state.
Uniformity test can be done at this state. When DRAIN icon is ressed, solenoid valve will drain fuel.
2) The system ressure can be adjusted by ressing + or – at testing.
3) During o erating, the user can select arameter, such as RPM or PW, and then ress or key to achieve the
status of the simulation.
4) Good injectors may have identical injecting angle, uniform s raying but no jet. Otherwise, re lace the injector.
5) In the s rayability test, a s ecial electrical arameter--the minimum injection ulse width of injector--can be
tested, to com are the injectors on the same engine. That is to set cylinder No., start the test from minimum
injection ulse width, and then gradually increases the ulse width till the injector starts injection (observed with
the hel of backlight). The value set at this moment is the minimum injection ulse width, so the difference of
minimum injection ulse width among these injectors could be observed.
Backflushing
Backflushing is limited to the to -su ly injector by connecting the backflushing connector under uniformity /
s rayability test. Test solution enters from the outlet of the injector and flows out from the inlet during backflushing.
Backflushing can wash away the dirt inside the injector and dirt attached to the filter.
1) Find the backflushing connector (and select a su orting “O” ring to install it on the connector) installed below
the fuel se arator;
2) Install the to -su ly injector in reverse direction (outlet u , inlet down);
3) Select the corres onding cou ling element under the injector according to the sha e of injector;
4) Adjust the screws to fix the fuel se arator and injector assembly in the fuel filler hole of the u er cover according
to the height of injector and tighten the com ression screws (black) on both sides evenly;
5) It is recommended to ress [Drain] button to drain the remaining fuel in the trans arent tube to avoid overflow
of test solution before backflushing.
6) Connect the ulse signal line of the injector ro erly; set the o erating arameters and ress Run button to
execute backflushing function; the system ressure can be adjusted by + and – buttons on the control anel
during backflushing.
7) The system will sto automatically after com letion of the cleaning.
