Unit injector inspection
Professional bench testing of unit injectors to determine their condition and compliance with factory specifications.
- Bench test
The unit injector is tested on a specialised bench that simulates real engine operating modes. The test shows whether it works correctly and how much fuel it delivers. - Fault detection
The test reveals wear, deviations from factory specifications or hidden defects that affect engine starting, smooth running and fuel consumption. - Results and recommendations
After the test, you receive full information on the condition of the unit injector and recommendations: continued use, repair or replacement. - Documentation
Based on the bench test, we provide a test plan or a diagnostic report confirming the actual condition of the unit injector.
