摘　　要：通过对93#汽油、0#柴油和95%的乙醇的自由燃烧试验,得出了3种燃料的燃烧特性,包括液层温度、质量损失速率、燃烧速度、密度、热释放速率、火焰温度等,并结合理论公式拟合热释放速率随油盘直径变化的曲线。质量损失速率与火焰高度汽油>柴油>乙醇;汽油、柴油、乙醇燃烧时的液面温度分别为125、310、80℃;3种燃料都在2 min以后达到稳定燃烧状态。The combustion performance of three kinds of fuel as 93# gasoline,0# diesel and 95% ethanol were test by free-burning test.The combustion performance includes reservoir temperature,mass lose rate,burning rate,density,heat release rate and flame height,etc.The curve of heat release rate changes with diameter of pool was fitting combine with theoretical formula.For mass loss rate and flame height,gasolinedieselethanol;The reservoir temperature of gasoline and diesel and ethanol are 125 and 310 and 80 ℃;All the 3 fuel burned stably after 2 min.
