摘要

汽车保有量的快速增长带来了污染物排放量的增加,掺入醇类可以有效减少柴油发动机的常规污染物排放。然而,醇类与柴油的互溶性较差。本研究以生物柴油为助溶剂,研究了掺入不同醇类对柴油喷射和燃烧特性的影响。结果表明,在三种醇类中,掺入甲醇对气液相喷雾特性的改善效果最好,其次是乙醇和丙醇。甲醇混合物的 GL-SCA 和 GL-SPA 分别比乙醇混合物大 8.2 % 和 2.3 %,比丙醇混合物大 19 % 和 11.9 %。在四种燃料中,甲醇混合燃料的归一化 KL 总排放量最少,比柴油少 45%,比乙醇混合燃料少 23.8%,比丙醇混合燃料少 35.3%。

Optical study on the spray and combustion characteristics of diesel-biodiesel-alcohol blend fuels on a constant volume combustion chamber

The rapid increase in automobile ownership has brought about an increase in pollutant emissions, the blending of alcohols can effectively reduce conventional pollutant emissions from diesel engines. However, alcohols have poor inter-solubility with diesel fuel. This study investigates the effects of blending different alcohols on the spray and combustion characteristics of diesel, with biodiesel as the cosolvent. The results show that among the three alcohols, blending methanol has the best improvement in the gas-liquid phase spray characteristics, followed by ethanol and propanol. The GL-SCA and GL-SPA of the methanol blends are 8.2 % and 2.3 % larger than those of the ethanol blends, and 19 % and 11.9 % larger than those of the propanol blends, respectively. Among the four fuels, fuel blended with methanol emits the least normalized sum KL, 45 % less than that of diesel, 23.8 % less than that of ethanol blended fuel, and 35.3 % less than that of propanol blended fuel.
