摘要
应用零维单区内燃机模型对新生物替代燃料2,5-二甲基呋喃(DMF)的燃烧性能和化学动力学过程进行数值模拟分析。在研究DMF燃烧化学动力学过程的基础上,分析了DMF燃烧时不同进气温度和过量空气系数对缸内温度、着火时刻和NOx排放量的影响,结果表明:进气温度增加40 K可使着火时刻提前20°CA;与正庚烷的燃烧对比可知,在上止点附近着火时DMF需要较高的进气温度;过量空气系数对燃烧的影响表明,DMF可以在低温压燃条件下使用,并且有低的NOx排放。
Numerical simulation and analysis on chemical kinetics and combustion performance of new bio -fuel 2,5-dimethylfuran （ DMF） was performed by using single -zone model coupled with detailed kinetic model .Based on chemical kinetics study on DMF, the influence of intake temperature and excess air coefficient on combustion performance of DMF was studied . The results show that ignition time advanced 20°CA when intake temperature improved 40K;DMF needs higher intake temperature to make it fire before the TDC compared with n -heptane under the same situation; study on excess air coefficient shows DMF can burn under low temperature and has low NOx emission .
