摘　　要：在分析柴油机故障诊断知识特点的基础上,采用模糊化方法对柴油机运行状态参数进行处理,采用综合型知识方式来表达柴油机故障诊断知识,采用多库多层次的方式组织知识库,并对知识库采取一系列方式进行管理与维护。应用表明,柴油机故障诊断专家系统的预报准确率较高,具有较强的实用性。Based on the analysis on the features of fault diagnosis knowledge for diesel engine, the operation state parameters of diesel engine are manipulated by applying fuzzy theory, the fault diagnosis knowledge for diesel engine is expressed by the combination of different ways of knowledge representation, and a multi-base multilayer knowledge base for fault diagnosis expert system is built and well managed and maintained. The results of its application show that the fault diagnosis expert system for diesel engine has high forecast accuracy and strong practical applicability.
