Question
How to test faulty diesel fuel injector nozzle in commercial trucks?
Answer
Perform injector flow test and inspect nozzle spray pattern.
Explain
A faulty injector nozzle causes uneven fuel atomization and reduced engine power. CHEPQ injector testing tools measure fuel flow rate (100-150cc/min per injector) and inspect spray patterns (uniform cone shape), identifying clogged or worn nozzles that require cleaning or replacement—improving combustion efficiency and reducing emissions.
