During operating, the user can select parameter, such as RPM or PW, and then press

status of the simulation.

Good injectors may have identical injecting angle, uniform spraying but no jet. Otherwise, replace the injector.

In the sprayability test, a special electrical parameter--the minimum injection pulse width of injector--can be tested,

to compare the injectors on the same engine. That is to set cylinder No., start the test from minimum injection

pulse width, and then gradually increases the pulse width till the injector starts injection (observed with the help

of backlight). The value set at this moment is the minimum injection pulse width, so the difference of minimum

injection pulse width among these injectors could be observed.

Backflushing

Backflushing is limited to the top-supply injector by connecting the backflushing connector under uniformity /

sprayability 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 supporting "O" ring to install it on the connector) installed below

the fuel separator;

2）Install the top-supply injector in reverse direction (outlet up, inlet down);

3）Select the corresponding coupling element under the injector according to the shape of injector;

4）Adjust the screws to fix the fuel separator and injector assembly in the fuel filler hole of the upper cover according

to the height of injector and tighten the compression screws (black) on both sides evenly;

5）It is recommended to drain the remaining fuel in the transparent tube to avoid overflow of test solution before

backflushing.

6）Connect the pulse signal line of the injector properly; set the operating parameters and press Run key to execute

backflushing function; the system pressure can be adjusted by

7）The system will stop automatically after completion of the cleaning.

5.4 Leakage Test

Leakage test is to inspect the sealing conditions of the injector needle valve under system pressure and to find out if

the injector is dribbling

Procedures

Installation refer to Uniformity/ Sprayability Test.

Before doing leakage test, please drain the rudimental residual test liquid from the measuring cup.

Select Leakage Test function and press Run key to start.

At this time the system pressure can be adjusted by pressing

the pressure is adjusted preferably 10% higher than manufacturer's specifications.

When the test is over, the equipment will automatically stop and the buzzer will ring simultaneously.

Note:In general the drip of the injector should be less than 1 drop within 1 minute (or in accordance with the

specifications). The default time of the system is 1 minute.
