摘　　要：液氮汽车作为一种环保交通工具 ,与电动汽车相比 ,具有很多优点 ,亦是当前环保汽车的一大发展趋势。目前国内对液氮汽车的研究基本上还是空白 ,国外的研究也是刚刚起步。文章在阐述液氮汽车研究现状的同时 ,得出现有液氮汽车系统中存在的主要问题 ,并提出解决现有问题的技术措施 ,探索新型循环系统的原理以及各关键部件和过程的优化模型 。As an environmental friendly transport tool, the vehicles powered by liquid nitrogen have more advantages compared with electric vehicles. Using this kind of vehicles is a tendency towards the development of vehicles beneficial to environment. Basically the research on the vehicles powered by liquid nitrogen in our country is still a blank in this respect and this research abroad just sets about making experiments. The paper describes the current status of developing the liquid nitrogen powered vehicles and points out key problems in the existing systems of liquid nitrogen powered vehicles. At the same time certain measures to be taken to solve these problems are set forth. In addition the principles of a novel circulation system and optimization models of key components and processes are investigated so that theoretical evidence can be provided for the development of practical and environmental friendly vehicles powered by liquid nitrogen
