Simulate the working conditions
and fuel injection volume of the
engine when the fuel injection
nozzle works for a certain number
of times when the engine is idling.

Flow balance Test the flow balance
at different speeds. When the liquid
level in the measuring cylinder is
2/3 of the measuring cylinder,
pause or stop work to observe the
balance of the fuel injection
volume. The deviation of the fuel
injection volume of all fuel injection
nozzles on a vehicle should not
exceed 2%. Or refer to the relevant
technical manual of the fuel
injector to judge the flow balance
of the fuel injector.
Observation of fuel injection shape
Observe whether the fuel injection
shapes and angles of all fuel
injection nozzles on the same car
are uniform at various speeds. At the
same time, you can adjust the
opening pulse width of the fuel
injection nozzle to check whether the
minimum opening pulse width of the
fuel injection nozzle is consistent.
Leak detection test Leak detection
test is to detect the tightness of the
injector needle valve under the high
pressure of the system. (Observe the
tightness of the fuel injector,
generally there should be no leakage
within one minute)
NOTICE：
Select “10 High Spray Volume”.
The rest of the operation steps are
consistent with item 08.
10 High Speed Spray Volume Test
After the test, raise the drain
handle and put the testing agent
back into the tank.
Select “09 Medium Spray Volume”.
The rest of the operation steps are
consistent with item 08.
09 Medium Speed Spray Volume Test
Display the product number and date
of manufacture of the device.
Turn off the power and unplug the
power plug.
Put all connectors back into the
accessory box for storage.
Drain the ultrasonic cleaning agent.
Wipe the equipment clean with a dry
soft cloth.
If the machine needs to be stored for
a long time, discharge the testing
agent into a bottle and seal it.
4.2 Maintenance
Replacement of testing agent After
the testing agent has been used for a
period of time, a lot of impurities will
