Abstract
Classification of diagnosis knowledge for Common Rail System(CRS) was investigated in this paper. Main fault modes and judgement regulations of CRS were confirmed throng principle of expert system. A scan tool was designed to communicate with vehicle Electronic Control Unit(ECU), and data link between scanner and ECU was realized through K-line communication, moreover, diagnosis program was accomplished based on Key Word Protocol 2000(KWP2000).
This study focused on methods to validate faults of CRS based on expert system. Method advanced was effective on fault diagnosis because expert system had capability of intellectual faculties. Finally, experiments were carried out on a six-cylinder diesel.
