液体燃料液滴的蒸发和燃烧过程是发动机实现高效清洁燃烧的重要环节。本文通过对比飞滴法、悬浮法、依附法和悬挂法4种常用液滴蒸发和燃烧试验研究方法，阐述和分析了每种方法的优缺点。从液滴蒸发和燃烧特性两个方面展开综述，详细介绍了发动机替代燃料液滴的蒸发和燃烧研究进展及存在的主要问题。最后对液滴蒸发和燃烧试验研究的未来发展方向进行了展望，期望为发动机清洁高效燃烧的研究提供借鉴和参考

The evaporation and combustion process of liquid fuel droplets is an important link for the engine to achieve efficient and clean combustion. This paper describes and analyzes the advantages and disadvantages of four commonly used droplet evaporation and combustion experimental methods, such as free falling method, suspension method, attachment method and fiber support method. The droplet evaporation and combustion characteristics are reviewed, and the research progress and main problems of droplet evaporation and combustion of engine alternative fuel are introduced in detail. Finally, the future development direction of droplet evaporation and combustion experiment research is prospected, which is expected to provide reference for the research of clean and efficient combustion of engine.
