minimum injection pulse width among these
injectors could be observed.
Reverse flush
iSmartINC 402 can also perform reverse flush by connecting
with flush-back adaptor at [Uniformity/Sprayability test]
mode. Reverse flush is a way to clean the injectors with the
test liquid flowing from the outlet to the inlet of the injector.
Reverse flush may remove the dirt inside the injector or the
injector Strainer (Only for the top fuel supply injector).
Procedures:
1)
Choose a reverse flush coupler and proper O-ring,
and mount them under the fuel distributor.
2)
Install the injectors in reverse direction (outlet
upward, and inlet downward).
3)
Choose a proper coupler according to the shape of
the injector and put it under the injector.
4)
Install the fuel distributor and the injector on the
fuel distributor supporter with a proper adjustable
screw and knurled nuts, and tighten two riffle
screws (black). See Fig. 06
5)
Connect the injector pulse signal wire.
6)
Set parameter, and press [Run] button to start
cleaning(iSmartINC 402 can switch between
reverse flush by pressing [Drain] key when it is
running press the
[ ]
key then press run key the
system pressure will come back to the default
pressure value When the function of item section
is working).
7)
When the cleaning is over, iSmartINC 402 will
automatically stop at the ring of the buzzer.
Note:
The system pressure can be adjusted by pressing
[decrease pressure]/[increase pressure] key when
performing reverse flush.
It is advisable to press [Drain] key to avoid
spillover of test liquid during reverse flush.

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 (For installation refer to
Uniformity/
Sprayability Test
):
1) Before doing leakage test, please press [Drain]
button to drain the rudimental residual test liquid
from the measuring cup.
2) Select [Leakage test] mode on the control panel.
Press [run] key, the machine will work. At this time
the system pressure can be adjusted by pressing
[decrease pressure]/[increase pressure] key to
observe dribbling from the injector the pressure is
adjusted preferably 10% higher than manufacturer’s
specifications(iSmartINC 402 can switch
between
leakage test
by pressing [Drain] key when it is
running press the

key then press run key the
system pressure will come back to the default
pressure value When the function of item section is
working).
3) 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.
Injecting Flow Test
Injecting flow test is to check if the injecting flow in 15
seconds meets the specifications for injecting amount.
The deviation reflects the wear or clogging in the injector,
instead of electrical parameter variation.
Procedures
(For installation refer to
Uniformity / Sprayability Test
):
1) Before this test, press [Drain] button to drain the
test liquid from the measuring cup if there is any.
2) Choose [Injecting flow test] mode on the control
panel, and press [Run] button to start the test.
Adjust the fuel pressure by pressing [decrease
pressure]/[increase pressure] key according to the
injector specification(iSmartINC 402 can switch
between injecting flow test
by pressing [Drain]
key when it is running press the
[ ]
key then
press run key the system pressure will come back
to the default pressure value When the function of
item section is working).
3) When the test is over, iSmartINC 402 will stop
automatically at the ring of the buzzer.
Auto. Test
Auto. test contains all above-mentioned tests (15-second
injecting test, idle speed, middle speed, high speed,
varying acceleration, varying deceleration, changing
pulse width test). This function can test more
comprehensive performance of injectors by simulating
the various engine working conditions.
