Abstract

Fossil fuel usage causes environmental pollution, and fuel depletion, further affecting a country’s economy. Biofuels and diesel-blended fuels are practical alternatives to sustain fossil fuels. This experimental study analyses lemongrass oil’s performance, emissions, and combustion characteristics after blending with diesel. Lemongrass oil is mixed with diesel at 10 (B10), 15 (B15), and 25% (B25) and evaluated using a 5.20 kW direct injection diesel engine. B10 brake thermal efficiency is 36.47%, which is higher than other blends. The B10 displays an 8.73% decrease in brake-specific fuel consumption compared to diesel. An increase in exhaust gas temperature for B10 than diesel is 4.5%. It indicates that higher lemongrass oil blends decrease exhaust gas temperature. The decrease in average carbon monoxide emissions in B10 to diesel is 22.19%. The decrease in hydrocarbon emissions for B10 to diesel is 7.14%. Biodiesel with lemongrass oil increases nitrogen oxide (NOx) because of increased temperature and poor combustion. Apart from NOx emissions, all other parameters of lemongrass oil blends are suitable for practical diesel applications. The significant findings benefit the biodiesel community toward the efficient combustion of biodiesel blends.

以柠檬草油生物柴油-柴油混合物为动力的传统柴油发动机的发动机性能分析

化石燃料的使用会造成环境污染和燃料枯竭，进一步影响国家经济。生物燃料和柴油混合燃料是维持化石燃料的实用替代品。本实验研究分析了香茅油与柴油混合后的性能、排放和燃烧特性。柠檬草油与柴油的混合比例为 10 (B10)、15 (B15) 和 25% (B25)，并使用 5.20 千瓦直喷式柴油发动机进行了评估。B10 的制动热效率为 36.47%，高于其他混合物。与柴油相比，B10 的制动油耗降低了 8.73%。B10 的废气温度比柴油提高了 4.5%。这表明柠檬草油混合物越高，废气温度越低。与柴油相比，B10 的平均一氧化碳排放量减少了 22.19%。B10 与柴油相比，碳氢化合物排放量减少了 7.14%。添加柠檬草油的生物柴油会增加氮氧化物（NOx），原因是温度升高和燃烧不良。除氮氧化物排放外，柠檬草油混合物的所有其他参数都适合实际柴油应用。这些重要发现有利于生物柴油界实现生物柴油混合物的高效燃烧。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
