Abstract

In this study, the effects of adding different proportions of TiO₂, Ag₂O, and CeO₂ nanoparticles to a three-cylinder, water-cooled, four-stroke, direct injection diesel engine on engine performance and exhaust emissions are experimentally investigated. The experiments are conducted at four different engine loads (10, 20, 30, and 40 Nm) and a constant engine speed (1800 rpm). TiO₂, Ag₂O, and CeO₂ nanoparticles are added to the diesel fuel at concentrations of 50 and 75 ppm each. The test fuels used in the study are as follows: D100, DTi50, DTi75, DAg50, DAg75, DCe50 and DCe75. Using the experimental results, analyses of energy, exergy, sustainability, greenhouse gas (GHG) emission impact, and cost are performed. The experimental results reveal that the use of nanoparticles in diesel fuel reduces BSFC. The highest reduction in BSFC is achieved with DTi75 fuel, averaging 9 %. Additionally, DTi75 fuel shows an average increase of 19 % in NO_x emissions compared to D100 fuel, while smoke emissions decrease by an average of 30 %. The highest average increase in exergy efficiency compared to D100 fuel is obtained with DAg50 fuel (5.6 %), followed by DTi75 fuel (5.3 %). The addition of nanoparticles to diesel fuel also leads to an increase in GHG emissions. Compared to D100 fuel, the highest average contribution to GHG emissions increase is shown by DTi75 fuel (12 %), while the lowest average contribution is observed with DAg50 fuel (4 %).

使用不同比例的 TiO2、Ag2O 和 CeO2 纳米添加剂的柴油发动机的权衡评估、能效和温室气体影响成本分析

本研究通过实验研究了在三缸水冷四冲程直喷式柴油发动机中添加不同比例的 TiO2、Ag2O 和 CeO2 纳米粒子对发动机性能和废气排放的影响。实验在四种不同的发动机负荷（10、20、30 和 40 牛米）和恒定的发动机转速（1800 转/分钟）下进行。在柴油中分别添加了浓度为 50 和 75 ppm 的 TiO2、Ag2O 和 CeO2 纳米粒子。研究中使用的测试燃料如下：D100、DTi50、DTi75、DAg50、DAg75、DCe50 和 DCe75。利用实验结果，对能量、放能、可持续性、温室气体（GHG）排放影响和成本进行了分析。实验结果表明，在柴油中使用纳米颗粒可降低 BSFC。DTi75 燃料的 BSFC 降低幅度最大，平均为 9%。此外，与 D100 燃料相比，DTi75 燃料的氮氧化物排放量平均增加了 19%，而烟雾排放量平均减少了 30%。与 D100 燃料相比，DAg50 燃料的放能效平均增幅最高（5.6%），其次是 DTi75 燃料（5.3%）。在柴油中添加纳米颗粒也会导致温室气体排放量的增加。与 D100 燃料相比，DTi75 燃料对温室气体排放增加的平均贡献率最高（12%），而 DAg50 燃料的平均贡献率最低（4%）。

期刊介绍： Energy is a multidisciplinary, international journal that publishes research and analysis in the field of energy engineering. Our aim is to become a leading peer-reviewed platform and a trusted source of information for energy-related topics. The journal covers a range of areas including mechanical engineering, thermal sciences, and energy analysis. We are particularly interested in research on energy modelling, prediction, integrated energy systems, planning, and management. Additionally, we welcome papers on energy conservation, efficiency, biomass and bioenergy, renewable energy, electricity supply and demand, energy storage, buildings, and economic and policy issues. These topics should align with our broader multidisciplinary focus.
