FUEL INJECTOR TESTING

Use applicable procedures to evaluate supported injector condition and performance.

DCT SERVICE PROCESS / STEP 02

FUEL INJECTOR TESTING

Injector families differ. Appropriate test conditions, opening behavior, flow and leakage observations must be chosen for the actual system rather than assumed from vehicle branding.

What this step can involve

  • Identify the injector system and exact model
  • Select test procedure supported by the equipment and parts
  • Explain results and limits of what the bench test establishes
  • Decide if repair, rebuilding, cleaning or replacement merits discussion

The exact work varies with the component and is subject to confirmed eligibility, applicable procedures, available parts and customer authorization.

These six stages explain the overall fuel-injection workflow. A specific component may require only some of them. Service scope is decided after evaluation and approval.

TECHNICAL DETAIL / CONNECTED SERVICE PROCESS

THE CORRECT INJECTOR TEST DEPENDS ON THE TECHNOLOGY

DCT uses the component family, reported concerns and supported test procedure to determine which stages apply. No stage is automatically included or approved by a submitted inquiry.

  1. 01

    Mechanical units may need opening-pressure, spray pattern and leakage checks.

  2. 02

    Common-rail units may require electrical response, delivery and back-leak checks.

  3. 03

    EUI/HEUI systems require attention to their own actuation and control design.

  4. 04

    Results must be interpreted against the part number and a supported test procedure.

A useful distinction

A mechanical pop test should not be represented as a universal common-rail injector test. The available measurements and conclusions are different.
