摘要:
为了解不同着火性质燃料之间的相互作用,在定容燃烧弹上结合高压燃油共轨系统,通过高速摄像光学 系统,研究了柴油分别在两种不同的单碳高辛烷值燃料氛围下的着火和燃烧行为.结果表明:降低环境温度和增 加预混甲烷的浓度均延长柴油着火滞燃期,增大燃烧放热率峰值,且较低的环境温度和高的甲烷浓度有利于减少 碳烟的生成;相比于甲烷,甲醇对柴油着火的抑制作用更强,具有较长的滞燃期,为油气混合赢得更多的时间, 预混燃烧部分增加,因此柴油在甲醇氛围下的放热率峰值略高于甲烷氛围,同时产生碳烟的扩散燃烧比例降低, 生成的碳烟减少.
Abstract:
In order to understand the interaction between fuels of different ignition properties,the ignition and combustion characteristics of diesel injected in either methanol or methane mixture were researched in a constant volume combustion chamber coupled with high pressure common rail system by using high speed camera optical system.The premixed atmospheres are the mixture of methane and the mixture of methanol and air, respectively.Results show that the ignition delay period and the peak combustion release heat rate increase as the ambient temperature decreases or the premixed methane concentration increases.Under low ambient temperature or premixed methane atmosphere,the soot formation decreases.Compared with methane,methanol has a greater inhibitory effect on diesel ignition,so the ignition delay period of the methanol atmosphere is longer than that of the methane atmosphere.There are much time for diesel fuel to mix with air,so the peak release heat rate of the methanol atmosphere is bigger and less soot is generated.
