Research on fault diagnosis expert system of automotive engine based on ontology

The concept of Ontology has been introduced into engineering fields, including the Fault Diagnosis Expert System with artificial intelligence. Ontology as expression of domain knowledge can provide a new method for building expert system. Focusing on fault diagnosis of automotive engine, Domain-ontology-building, Fault-Diagnosis-System-Construction, and System-Reasoning-Description, are discussed in this paper, based on these, a complete fault diagnosis expert system of an automotive engine has been built as well.
