| 摘 要： | 随着海拔高度的增加,大气压力降低,导致柴油机的过量空气系数减小;柴油机在进行EGR后,过量空气系数减小的幅度增加,使得柴油机的各项工作特性参数发生不同程度的变化。使用内燃机大气模拟综合系统,初步探索了柴油机运行在不同海拔下进行EGR后,其经济性和烟度的变化规律,为今后在高原地区运行的柴油机采用EGR以及EGR技术的进一步研究提供了初步依据。

| Abstract: | With the increasing of altitude and decreasing of atmospheric pressure,the coefficient of excess of air of diesel is decreased,butafter using EGR,the range of decreasing of the coefficient of excess of airisincreased,the result is that the best of EGR`s rateis changed.Using IEair si mulation synthetically systemwhichisinIElabin Kunming University of Technology and Science,after applying EGR,theauthor researches the regulation of variation of economic performance and smokeintensity of the diesel which moving at different altitude,received conclusion provides basis for further study and practice. |
