摘要

大量的人口和汽车的扩张导致了能源需求的快速增长。由于对能源的高需求和化石燃料的迅速消耗，专家们正集中精力开发一种合适的替代柴油的燃料。采用纳米氧化镧(La2O3)对西瓜甲酯制备生物柴油的性能和排放特性进行了研究。以非食用西瓜籽油为原料，采用酯交换法制备生物柴油。与B20相比，在生物柴油乳液燃料中添加百万分之一百(ppm)的La2O3纳米颗粒，CO和HC的排放量分别减少4.75%和6.67%。与满载情况下的B20相比，添加100 ppm的La2O3纳米颗粒可使制动热效率(BTE)和制动比油耗(BSFC)分别提高2%和8.8%。

Influence of nano additives on performance and emissions characteristics of a diesel engine fueled with watermelon methyl ester

Significant population and automobile expansion have resulted in a rapid rise in energy demand. Because of the high demand for energy and the rapid depletion of fossil fuels, experts are concentrating their efforts on developing a suitable alternative fuel for diesel. The performance and emission characteristics of biodiesel made from watermelon methyl ester were investigated using a lanthanum oxide (La2O3) nanoparticle addition. Through the transesterification meth od, biodiesel was produced from non-edible watermelon seed oil. Compared to B20, addition of 100 parts per million (ppm) of La2O3 nanoparticles to biodiesel emulsion fuel reduces CO and HC emissions by 4.75% and 6.67%, respectively. Compared to B20 at full load circumstances, the inclusion of La2O3 nanoparticles at 100 ppm enhances the brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) by 2% and 8.8%, respectively.

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.
