摘　　要：依据单一的专家系统或神经网络在处理故障诊断中各自存在着局限性,提出了将神经网络技术与专家系统融合的集成式故障诊断专家系统,并应用于发动机故障诊断中。文章介绍了神经网络专家系统特点、结构、及诊断方法,并对4105ZD发动机在不同的工况下进行测试,测试结果表明,诊断系统能够对发动机常见故障取得良好的诊断效果。In the light of the limitations of a single expert system or neural network on fault diagnosis, A fault diagnosis system has estab- lished which integrated the expert system and the neural network. And it was applied in fault diagnosis of engine. A neural network expert system characteristics, structure and diagnostic methods were introduced, and the 4105ZD engine was tested in different working conditions. The test results show that the diagnosis system can obtain good diagnosis effect for the common faults of engine.
