Test bench cleaning fuel injectors

Cleaning injectors off a vehicle

When removing fuel injectors from the engine take careto:
when engine is runing we cold not take out the fuel injector because high presure should be damage or skin and cold fire because engine is hot and also high voltage .
when we removing fuel injector from vehicle the ignition is should off and make shure the engine is not hot causing fire .
Injectors had no leakage
Injectors flow rate  32 cc   we set the in secend wich the flow rate in 32cc in 10.2 second.

Test result in below chart:

Injector number Condition	1 OK	2 OK	3 OK	4 OK
Spray Pattern	OK	OK	OK	Poor(no-good)
Flow Rate	32cc	32cc	32cc	29cc
Leakage (dribble)	NO	NO	NO	NO

How many injectors require attention?  Only one wich is the no 4

Analaysing results
Describe the condition of all the injectors that you tested?
Only one injector which is no 4 need attintion , I think the pluge of injector is faulty because the spray pattren is poor atomosition , and also the flow is low then the other injectors the other injectors flow rates are same wich is inthis testing 32cc and this no4 is 29cc .
The other three has same flow rate same spray pattren in good even cone shape also these 4 injectors have no lekage.
