中文摘要：

针对目前油液监测故障诊断智能化、自动化遇到的困难，将知识工程的思想引入到油液监测中，并详细阐述了知识获取、知识表达、知识推理和知识利用在油液监测中的应用，最后将油液监测、知识工程、计算机技术结合起来建立了油液监测知识工程模型，为实现油液监测故障诊断自动化打下了基础。

英文摘要：

For the difficulties in the intelligentization and automatization of oil monitoring and fault diagnosis, knowledge engineering was introduced to oil monitoring, and the application of knowledge engineering, including knowledge acquisition, knowledge expression, knowledge reasoning, knowledge using in oil monitoring was expatiated. With the linking of oil monitoring, knowledge engineering and computer technology, the oil monitoring knowledge engineering model was established,which is important in the realization of oil monitoring and fault diagnosis＇ automatization.
