| 摘 要： | 研究了多点电喷汽油机燃用醇汽油混合燃料的性能。研究结果表明:在汽油机参数未做任何调整的情况下,醇汽油混合燃料发动机的动力性与汽油机相比有所降低,燃料经济性改善,有效热效率提高。随醇类燃料体积分数的增大,CO排放明显改善,THC排放略有升高,NOx排放的变化不明显。醇汽油混合燃料发动机的醛类排放物明显升高,汽油机的未燃甲醇排放较高,未燃乙醇排放变化不明显。

| Abstract: | The engine performance was investigated in a multipoint EFI gasoline engine fueled with gasohol blend. The results show that the power performance of gasohol blend engine is slightly lower than that of gasoline engine. The fuel economy of gasohol blend engine is more superior, and the thermal efficient is higher. With the volume fraction of alcohol increasing, CO emissions evidently decrease. THC emissions slightly increase, and NOx emission almost keeps constant. The aldehydes emissions of gasohol engine evi dently increase, the methanol emissions of gasoline engine are higher, and the ethanol emissions vary slight ly. |
