摘　　要：通常内燃机的基础研究采用试验、仿真和理论计算相结合的方法进行。近年来,随着燃烧光学可视化技术的日益发展,通过燃烧可视化测试,可对内燃机的喷雾、雾化、混合、点火、燃烧及排放机理进行深入探索,并对指导内燃机设计和仿真计算模型提供有力的数据支持。重点介绍了LIF和LII测试方法在内燃机基础测试装置上的应用,结合在定容燃烧弹上的光学测试,系统阐述了燃烧光学可视化技术在内燃机基础研究中的必要性和有效性,并对燃烧光学可视化技术未来的应用前景进行了展望。Usually internal combustion engine is studied by experiment, simulation and theoretical calculation. In recent years, with the increasing development of optical visualization technology, it can be used to research on the mechanism of spray, atomization, mixing, ignition, combustion and emissions of internal combustion engine. The application of LIF and LII testing method on the basis of internal combustion engine is introduced in this paper, combined with several application cases in constant volume combustion vessel. The necessity and validity of the combustion optical visualization technology in the basic research of internal combustion engine is discussed. The application future of combustion optical visualization technology is also prospected.
