摘　　要：系统介绍了双色法的测量原理,阐述国内外双色法在内燃机燃烧火焰分析方面的具体应用。经过多年研究,双色法已成功应用于柴油机燃烧诊断,利用燃烧火焰中实际存在的碳粒,可测量柴油机火焰的温度分布和碳烟浓度分布。汽油机属于无焰燃烧,燃烧过程只产生少量的碳烟,直接应用双色法具有较大难度,国内外可见文献较少,本文介绍了关于双色法汽油机测温的实例。This paper introduces the measurement principle of two-color method and its application in the combustion flame analysis around the world. On the basis of multiple years research, two-color method has been successfully used in diesel engines. The temperature distribution and the soot concentration distribution can be obtained by using the particles created in the combustion flame. The gasoline engine belongs to no flame combustion and produces little soot particles during combustion. So there is still great difficulty in using two-color method in gasoline engine. The papers on this topic around the world are few, so this paper introduces the examples of its usage in gasoline engine, including the author＇s research.
