为了提高发动机燃油经济性,对发动机废弃能量进行回收利用是一种比较有效的方法。综述了采用温差发电技术进行发动机能量回收的研究进展。在介绍温差发电技术基本原理的基础上,对其在发动机能量回收方面的应用历史进行了回顾,从发动机尾气能量回收和冷却系统能量回收两个方面进行了总结。指出了提高换热器效率、降低热阻、提升温差发电系统可靠性、基于温差发电技术生命周期评价等内容是未来研究的方向。

In order to develop the fuel economy of internal combustion engine, one of the efficient way was energy recycle of waste energy. So the status and development of energy recycle based on thermoelectric generation（TEG） was summarized. The fundamental of the TEG technology was introduced firstly, then the history and development of the TEG technology applied on internal combustion engine energy recycle were summarized and the summary was mainly about exhaust gas and cooler energy recycle. At the end the trends of TEG applied on engine energy recycle were summarized on how to increase hear exchange efficiency, reduce thermal resistant, improve reliability of TEG system and establish life cycle assessment.
