| 摘 要： | 提出乙醇重整燃料对发动机充气效率的影响的计算公式，可以预测完全燃用或者部分掺烧乙醇重整燃料对SI发动机充气效率和柴油机充气效率的影响。计算分析结果表明：乙醇重整燃料影响充气效率的主要因素是乙醇浓度和重整率，随着重整率的增加，乙醇重整发动机的充气效率有较大幅度下降，必将导致发动机的动力性能急剧下降，柴油机部分掺烧乙醇重整燃料对充气效率的影响较小。

| Abstract: | The formulas are presented,by which the effect of reformed-ethanol fuel on the volumetric efficiency in I.C.engines are able to be calculated.The results show that the main factors,which impact on the volumetric efficiency in the reformed ethanol engincs,are the concentration and the reforming coefficient of reformed ethanol;With increase in the reforming coefficient,it is found that there is a rapid decrease in the volumetric efficiency of the reformed ethanol engines,so the power output of the engines wou... |
