| 摘 要： | 为分析掺氢燃烧对天然气发动机的影响,给出3种不同的计算燃烧质量比曲线的R-W方法,由 Wiebe 函数模拟燃烧过程.采用这3种方法根据模拟压力计算出的燃烧质量比曲线和输入的 Wiebe 曲线相比,选取精度最高的方法对不同掺氢比的天然气发动机燃烧放热过程进行分析.研究结果表明:RW-3方法精度最高,随着掺氢比的增加,燃烧速度加快,燃烧过程明显缩短.

| Abstract: | In order to analyze the effect of hydrogen addition on the performance of natural gas engine,three different R-W methods for calculating combustion mass fraction were given first.Wiebe function was used to simulate the combustion process.The calculated combustion mass fraction using these three methods which were based on the simulated pressure was compared to that using the Wiebe function input,and the method with the best precision was selected to calculate the combustion mass fraction of natural gas engi... |
