摘　　要：简单介绍典型非常规内燃机的工作原理及独特结构;计算方法的进步和计算机技术的快速发展促进了计算流体力学在内燃机研制中的应用,减少了实验工作量,降低了研究费用,缩短了研发周期,Fluent软件突破了内燃机专用软件中对内燃机结构的限制,提供了用户自定义函数这一用户接口,为非常规内燃机的瞬态数值仿真计算提供了平台。非常规内燃机为提升内燃机热效率提供了发展思路,在非常规内燃机开发中应用Fluent进行数值模拟可加快研发进程。Many unconventional internal combustion engines have been proposed which greatly enhanced internal combustion engine （ICE） thermal efficiency. The working principles and unique structures of the typical unconventional ICEs are introduced respectively. The development of calculation methods and computer technology promotes the computational fluid dynamics application in ICE, which greatly decreases the experiments, reduces research cost, and shortens the development cycle. Fluent software breakthroughs the limits of ICE special software, and provides a user defined function （UDF） which can make user exchange data with the fluent interior. It supplies a platform for unconventional ICE transient numerical simulation. The technologies of unconventional ICE provide new ideas for the development of high efficiency ICE. The application of fluent in unconventional engines can speed up the development process of unconventional engines.
