摘　　要：本文详细介绍了汽车发动机故障诊断模糊专家系统的设计要点，模糊诊断知识的组织、模糊诊断推理、智能诊断程序结构，设计的诊断系统可根据模糊故障信号进行故障诊断，并由诊断结果获取相应维修方案。本系统使用模糊技术进行推理，能较好地处理诊断过程中的不确定性问题，该系统由C语言开发，在WINDOWS平台上运行。The key points in a fuzzy expert system for vehicle engine troubleshooting such as organization of fuzzy diagnosis knowledge, principle of fuzzy induction and program structure have been described. The engine default can be found by using fuzzy default signal and corresponding maintenance approach can be obatained from the measured results. The uncertain problem existed in the process of diagnosis can be naturally dealed with by using this system. All the programs in the system has been devloped in C language which can run in Window environments.
