Abstract

The growing concern about environmental degradation and the depletion of fossil fuel supplies has prompted experts to investigate alternate and sustainable transportation energy sources. In these circumstances, biodiesel made from renewable feedstock has emerged as a viable environmentally friendly alternative to conventional diesel. This study thoroughly examines the performance and emission characteristics of a 4-stroke diesel engine running on biodiesel blends, including reduced graphene oxide (rGO) nanomaterial. The non-edible biodiesel from the Jatropha curcas plant is utilized, and it is blended in various ratios with conventional diesel, ethanol, and nanomaterial rGO to improve performance and emissions parameters. Torque increased by up to 17 % in rGO DJE02GO25 at 3500 rpm, while Brake Power decreased by 6.3 % in rGO DJE01GO25 at 2600 rpm. Brake Thermal Efficiency decreased by 12.5 % in rGO Blend 1 at 2600 rpm, and Brake-specific fuel consumption decreased by 16.5 % in rGO DJE02GO25 at 3500 rpm. CO₂ emissions decreased up to 19.71 % in rGO Blend 10 at 2600 rpm. HC emissions decreased to 94 % in rGO blend 8 at 3500 rpm. Finally, NOx emissions decreased up to 84.78 % in rGO Blend 1 at 2900 rpm. The current study reveals that after adding rGO nanomaterial in biodiesel, there is a significant decrease in NOx and HC emissions.

用还原氧化石墨烯和非食用生物柴油混合物提高柴油发动机性能并控制排放

人们对环境恶化和化石燃料供应枯竭的担忧与日俱增，促使专家们开始研究替代性和可持续的运输能源。在这种情况下，由可再生原料制成的生物柴油已成为传统柴油的一种可行的环保型替代品。本研究深入研究了使用生物柴油混合物（包括还原氧化石墨烯（rGO）纳米材料）的四冲程柴油发动机的性能和排放特性。研究利用麻风树（Jatropha curcas）植物制成的非食用生物柴油，并将其与传统柴油、乙醇和纳米材料 rGO 以不同比例混合，以改善性能和排放参数。在转速为 3500 rpm 时，rGO DJE02GO25 的扭矩增加了 17%，而在转速为 2600 rpm 时，rGO DJE01GO25 的制动功率降低了 6.3%。转速为 2600 rpm 时，rGO 混合燃料 1 的制动热效率降低了 12.5%；转速为 3500 rpm 时，rGO DJE02GO25 的制动油耗降低了 16.5%。转速为 2600 rpm 时，rGO 混合燃料 10 的二氧化碳排放量减少了 19.71%。转速为 3500 rpm 时，rGO 混合燃料 8 的 HC 排放量减少了 94%。最后，转速为 2900 rpm 时，rGO 混合物 1 的氮氧化物排放量减少了 84.78%。目前的研究表明，在生物柴油中添加 rGO 纳米材料后，氮氧化物和碳氢化合物的排放量显著减少。
