| 摘要:从试验及匹配角度出发，对燃烧E85与E0的发动机的排放及燃烧相关参数进行对比研究。结果表明:E85的HC、CO排放在各种工况下都优于E0；NOx排放在中小转速、中小充气效率下好于E0，其他转速、充气效率下NOx排放显著增加；E85燃烧放热速度快于E0；E85发动机全工况无爆震，实际点火角可以做到最优点火角。所得到的结果可作为E85发动机设计及发动机标定的依据。 |

| Abstract:Comparative analysis of the emission and combustion parameters of engines using E85 and E0 were carried out based on tests and calibrations. The results show that the HC and CO emissions of E85 are better than E0 under various working conditons; NOx emissions of E85 at medium and low speeds and volumetric efficiency are better than E0,but increase significantly at other speeds and volumetric efficiency; the combustion and heat release speed of E85 is faster than E0; no knocking occurred on E85 under all working conditions, and the ignition angle can be calibrated to be the same as the optimal angle.The research results can be used as the guidance for E85 engine design and engine calibration. |
