摘　　要：探讨了柴油机燃烧光强波的性质。在不同压力、氧浓度的条件下,对柴油、乳化油、甲醇喷雾的燃烧光强波进行了测量分析。结果表明,柴油机的燃烧光强波所反应的是火焰内碳粒的氧化历程。对于不同的燃料,燃烧光强波的强弱并不仅仅取决于火焰中碳粒的数量,同时还取决于火焰中的氧浓度。Properties of the combustion light intensity wave of diesel engines are discussed.Measure and analysis of combustion light intensity wave of diesel fuel,emulsified oil and nebulized methanal are carried out under different pres-sures and oxygen density.It is shown that what the combustion light intensity of diesel engine reflected is the oxidation course of carbon particles in flame.For various fuels,strength of combustion light wave is not only determined by quantity of carbon particles in flame,but also determined by oxygen density in flame.
