This research conducted the effect of different ethanol blends in a conventional gasoline engine under various load and speed conditions for its performance and emission characteristics. The experiment was tested on the test motorcycle designed initially to run by gasoline fuel. The experimental procedure was performed in the motorcycle testbed equipped, measuring power, fuel consumption, and exhaust emissions. NOx and HC emissions of the test vehicle using ethanol blends are lower than gasoline. However, NOx emissions have an opposite trend; they increased approximately 7.4% with E5, 12.3% with E10, and 18.51% with E20 due to the temperature increase. Furthermore, the ethanol contents provide the leaning effect to enhance the air-fuel equivalence ratio to a more excellent value and result in the burning closer to stoichiometric. As a result, improved combustion and increased power output are possible.: This paper aims to find out the solution to solve the problem related to the energy crisis and polluted environment from the motorcycles in Vietnam.
本研究在不同负荷和转速条件下，考察了不同乙醇混合燃料对传统汽油机的性能和排放特性的影响。该实验在最初设计为使用汽油燃料运行的测试摩托车上进行。实验程序在配备有测量功率、燃油消耗和废气排放的摩托车试验台上进行。与汽油相比，使用乙醇混合燃料的测试车辆的 NOx 和 HC 排放较低。然而，由于温度升高，NOx 排放呈相反趋势，E5 增加了约 7.4%，E10 增加了 12.3%，E20 增加了 18.51%。此外，乙醇含量提供了稀燃效果，使空燃当量比提高到更好的值，并导致燃烧更接近理论空燃比。因此，燃烧和功率输出都得到了改善。本文旨在从越南摩托车的角度出发，寻找解决能源危机和环境污染问题的方法。
