摘　　要：针对汽车发动机异响类故障是故障诊断的难点,应用“基于最大疑似度的概率统计”法对汽车发动机的异响类不确定性故障进行了推理诊断,并用更新知识库的方法实现了对电脑常见故障现象的故障诊断,推理结果与实际情况基本一致,证明“基于最大疑似度的概率统计”法应用于不确定性故障诊断科学有效。Difficult point diagnosed by the trouble to the different noises kind of troubles of the car engine, employ the method that ＂the probability based on biggest suspected degree is counted＂ to diagnose the trouble to the different noises kind of uncertain troubles of the car engine. And has realized with the method of newer knowledge base that diagnoses the trouble of the common trouble phenomenon of the computer, deduce result and actual conditions basically identical, prove ＂ based on biggest suspected degree probability count ＂ method apply to uncertain trouble it diagnoses to be science effective ＂

关 键 词：动力机械工程 不确定性网上故障诊断 分析 发动机 最大疑似度概率统计
