Diesel Injector Testing

For Diesel injectors, we use a computerized test bench to operate your injector in as close to real-world conditions as possible and accurately evaluate injector performance. It also tests Denso, Delphi, and Siemens injectors.

Our tests include high-pressure nozzle and control valve leak testing, injector start behavior, idle speed adjustment tuning, and full-load quantity.

From these tests, we identify which injectors need service or replacement and which are in good condition, -meaning you don’t have to spend more money replacing everything. 

Once your common rail injectors have been tested, you are ready to make an informed decision and often save hundreds of dollars.

Proper testing provides accurate evaluations, streamlines diagnostic troubleshooting, and helps get you and your customers back on the road faster!
