摘要:
ABE (丙酮-丁醇-乙醇,Acetone-Butanol-Ethanol,ABE)是发酵生成丁醇过程中的中间产物,来源广泛,价格低廉。本研究的目的是揭示ABE燃料在火花点燃发动机中的燃烧特性,并且希望证实它有潜力成为内燃机中替代燃料。丙酮,正丁醇和乙醇以3:6:1的体积比混合,然后与无酒精汽油以不同比例混合成不同的燃料。这些混合燃料在一台进气道喷射式汽油机上进行测试,它们的性能通过测量其气缸压力以及排放物的含量来进行评价。随着ABE成分的增加,有效燃油消耗率会有所增加,但NOx排放减少。若只使用ABE燃料,NOx排放可以几乎为零。

Abstract: ABE (Acetone-Butanol-Ethanol, ABE) fermentation is one of the major methods to produce bio- butanol. The goal of this study is to investigate the combustion characteristics of the intermediate product in the production of butanol, namely ABE in a spark-ignited engine and hence to make an attempt to affirm its potential used as an alternative fuel for ICEs. Acetone, n-butanol and ethanol were blended in a 3:6:1 volume ratio and then blended with pure ethanol-free gasoline with dif-ferent ratios to create various fuel blends. These blends were tested in a port-fuel injected spark ignited engine and their performance was evaluated through measurements of in-cylinder pressure, and various exhaust emissions. ABE is combusted faster than gasoline and n-butanol due to its higher laminar flame speed. Brake Special Fuel Consumption (BSFC) was seen to increase and NOx was seen to decrease with ABE fraction increasing, with pure ABE achieving near-zero NOx.
