Abstract: Intelligent Technique of Fault Diagnosis is a new fault analysis, which pays more
attention to doing research on the overall structure of the system and transmission relationship
between the different faults. Structure and behavior-based diagnosis is a thought breakthrough in
the intelligent diagnosis. It is a kind of model-based diagnosis. Modeling, diagnostic generation
and diagnostic tests are studied in depth and a diagnostic system which can be applied to the
actual production system is brought out. Then it is applied to the fault diagnosis of the intake
system of diesel engine.

Key words: fault diagnosis, fault location, structure and behavior-based diagnosis, Rodelica;
