Fuel injection case evidence is useful when it connects the customer complaint, component identification, appropriate measurements and authorized repair to a verifiable result. This guide explains the information to look for in a technical case record.
What a complete case record includes
- Engine, equipment and exact injector or injection pump identifier
- Operating symptoms and previous on-engine measurements
- Applicable test sequence and condition of the component as received
- Findings, tolerances and any uncertainty or incomplete test coverage
- Customer approval of service scope, repair actions and final verification
