摘要：在柴油机上进行柴油、三种生物乳化柴油（E10、E15和E20)和生物柴油的推进特性试验，就其燃烧特性、动力性、经济性及常规排放特性进行对比。试验结果显示：高转速时，生物乳化柴油的缸内燃烧压力和放热率略低于柴油，缸内燃烧温度有所降低；动力性相比柴油略有下降，仅E10 的燃油消耗率比柴油低,B100最高；烟度和NO，排放均有显著降低，且随水和丁醇掺混比例增加而降低：CO和HC排放与柴油基本无差别，整体增加不多。表明：生物乳化柴油作为替代燃料能保证
柴油机运行的稳定性，可同时降低柴油机的烟度和NO，排放，具有良好的环境效益和经济效益。关键词：生物乳化柴油；推进特性：试验；排放；经济性

Abstract: Diesel fuel , three kinds of bio-emulsified diesel (E10, E15, E20) and biodiesel were tested on a diesel engine under the propulsion characteristic condition . The combustion characteristic , power, economic , and emission characteristics of these five fuels were compared with each other . The results show that at full load , the combustion pressure and heat release rate of bio -emulsified diesels are slightly lower than that of diesel and the combustion temperature in the cylinder decreases , the power performance has a slight decrease compared with diesel. Only E1o has a lower fuel consumption rate than diesel , and B10 is the highest. NO emission and the smoke value decreased significantly as the mixing proportion of water and butanol increased. The CO and HC emissions of bio-emulsified diesels are basically indistin-guishable from diesel , and the overall increase is not much . It can be concluded that as an alternative fu -el, bio-emulsified diesel can guarantee the stability of diesel engine , and meanwhile reduce the smoke and NO, emission, which has good environmental and economic benefits .
Key words : bio-emulsified diesel ; propulsion characteristic ; test ; emissions ; economic performance
0引言
柴油机因其热效率高、经济性好、可靠性高等优点被广泛应用于汽车、船舶、工程机械等领域”。
但随着石油资源的日益紧缺和生态环境的不断恶化，传统柴油机的应用遇到了很多难题。如何在不改变现有柴油机结构的条件下，有效降低燃料消耗和减少污染物排放成为当前研究的重点之一。
