从环境和经济角度来看，广泛用于内燃机的醇是重要的可再生和可持续能源。此外，醇的生物生产减少了化石燃料的消耗。尽管有许多关于在内燃机中使用低级醇（例如甲醇和乙醇）的研究，但对高级醇的研究数量有限。丙醇、正丁醇和 1-戊醇等高级醇是下一代生物燃料的一部分，因为它们比低级醇提供更好的燃料特性。生物柴油-高级醇混合物可用于柴油发动机，无需对发动机进行任何改造，但需要在各种发动机条件下进行长期测试，以评估其对发动机性能和环境污染物的影响。本研究的目的是评估废油甲酯 (B100) 中使用丙醇、正丁醇和 1-戊醇对固定发动机转速 (1800 rpm) 下不同负载（0、3、6 和 9 kW）运行的柴油发动机的发动机性能和废气排放的影响。通过将丙醇、正丁醇和 1-戊醇 (10 vol.%) 添加到废油甲酯中，分别获得 B90Pr10、B90nB10 和 B90Pn10 的混合物来制备测试燃料混合物。根据发动机性能和废气排放结果，B100中添加丙醇、正丁醇和1-戊醇具有增加制动燃料消耗率和废气温度的效果。 B90Pr10和B90nB10的制动热效率（BTE）下降，而B90Pn10的BTE与B100相比略有增加。与B100相比，B90Pr10、B90nB10和B90Pn10在较低负载下一氧化碳排放量减少，而在9kW负载下略有增加。与 B100 相比，B90Pr10、B90nB10 和 B90Pn10 在整个负荷下观察到氮氧化物排放量的减少。当考虑所有负荷时，B90Pn10 呈现出最好的平均碳氢化合物排放量，减少了 45.41%。版权所有 © 2016 约翰·威利父子有限公司
Alcohols extensively used in internal combustion engines are important renewable and sustainable energy resources from environmental and economical perspectives. Besides, bio production of alcohols decreases consumption of fossil‐based fuels. Although there are many studies with regards to the use of lower alcohols such as methanol and ethanol in internal combustion engines, there are a limited number of investigations with higher alcohols. Higher alcohols such as propanol, n‐butanol, and 1‐pentanol are part of the next generation of biofuels, given they provide better fuel properties than lower alcohols. Biodiesel–higher alcohol blends can be used in diesel engines without any engine modification but need to be tested under various engine conditions with long periods in order to evaluate their impacts on engine performance and environmental pollutants. The objective of this study was to evaluate the effect of using propanol, n‐butanol, and 1‐pentanol in waste oil methyl ester (B100) on engine performance and exhaust emissions of a diesel engine running at different loads (0, 3, 6, and 9 kW) with a fixed engine speed (1800 rpm). Test fuel blends were prepared by adding propanol, n‐butanol, and 1‐pentanol (10 vol.%) into waste oil methyl ester to achieve blends of B90Pr10, B90nB10, and B90Pn10, respectively. According to engine performance and exhaust emissions results, the addition of propanol, n‐butanol, and 1‐pentanol to B100 had the effect of increasing brake specific fuel consumption and exhaust gas temperatures. The brake thermal efficiency (BTE) decreased for B90Pr10 and B90nB10, while B90Pn10 showed a slight increase in BTE as compared with B100. When compared with B100, B90Pr10, B90nB10, and B90Pn10 decreased carbon monoxide emissions at lower loads while it increased slightly at 9 kW load. The decrement in oxides of nitrogen emission was observed at whole loads for B90Pr10, B90nB10, and B90Pn10 compared with B100. When considering all loads, B90Pn10 presented the best mean hydrocarbon emission with a reduction of 45.41%. Copyright © 2016 John Wiley & Sons, Ltd.
