Modern commercial diesel systems use common rail injection or electronic unit injectors to control fuel delivery precisely. Correct diagnosis requires both electronic and mechanical testing.
Common rail & EUI capabilities
- Common rail injector testing
- EUI injector bench testing
- Actuator and electrical checks
- Nozzle and valve inspection
- Fuel delivery and return comparison
- Pressure and leakage evaluation
- Coding / calibration support where applicable
- Related wiring and ECU checks
Electronic and mechanical faults can overlap
An EUI or common rail issue may be caused by the injector itself, its electrical control, fuel supply, pressure system or engine-side mechanical condition. We compare test results with the vehicle symptom instead of relying on a single fault code.
