High-speed fuel injecting amount test" item.
●

NOTE
Uniformity
This is for checking the uniformity carried out at various rpm.
When the test liquid level is at 2/3 of the test tube, please
pause or stop the machine to observe the uniformity of the
injecting amount. Injecting difference of all injectors on one
vehicle should be kept within 2%. Or refer to the relevant
technical manual of the fuel injector to determine the uniformity
of the injecting amount.
Observe the shape of the injectors
Observe whether the injecting shapes and angles of all fuel
injectors on the same vehicle are identical at various speeds.
At the same time, you can adjust the injection pulse width of
the fuel injectors to compare whether the minimum injection
pulse width among the fuel injectors is consistent.
Leakage test
Leakage test is to inspect the sealing conditions of the injector
needle valve under system pressure. (Observe the tightness of
the fuel injectors, generally, there should be no leakage within
one minute.)
