摘要

在本实验研究中，分析了氧化铜纳米颗粒对以棕榈油生物柴油为动力的4.4 kW柴油机排放和性能的影响。将体积为20%的棕榈油生物柴油与柴油混合，所得混合物称为B20。B20测试燃料混合物中分别掺杂了浓度为25 ppm、50 ppm和75 ppm的CuO纳米颗粒。实验分别在0%、25%、50%、75%和100%发动机负荷下进行，转速恒定(1500转/分)。性能参数，如制动热效率(BTE)和制动比能耗(BSEC)，排放参数，如一氧化碳(CO)，二氧化碳(CO2)，碳氢化合物(HC)，氮氧化物(NOx)和烟雾不透明度进行了分析。结果表明，在B20共混物中加入纳米CuO后，BTE显著提高约1.18% ~ 7.69%，BSEC显著降低约4.12% ~ 6.76%。此外，当添加CuO纳米颗粒时，CO也有明显的降低(2.21% - 8.86%)。此外，与B20混合动力车相比，HC(0.3% 9.78%)、CO2(2.38% 5.97%)和NOx(1.75% 5.27%)的排放水平也明显增加。然而，与柴油相比，除了氮氧化物排放外，所有生物柴油混合物的排放水平都较低。综上所述，纳米氧化铜可以作为棕榈油生物柴油混合物的合适的石油添加剂。

Emission and Performance Characteristics of a Diesel Engine Using Copper Oxide Nanoparticles in Palm Oil Biodiesel-Diesel Blends

In the present experimental study, the influence of copper oxide (CuO) nanoparticles on emissions and performance of a 4.4 kW diesel engine powered by palm oil biodiesel have been analyzed. Palm oil biodiesel of 20% by volume was blended with diesel fuel and the resulting blend is termed as B20. The B20 test fuel blends were doped with CuO nanoparticles with concentrations of 25 ppm, 50 ppm, and 75 ppm. Experiments were carried out at 0%, 25%, 50%, 75%, and 100% engine loads at a constant speed (1,500 rpm). Performance parameters such as brake thermal efficiency (BTE) and brake specific energy consumption (BSEC), emission parameters such as carbon monoxide (CO), carbon dioxide (CO2), hydrocarbons (HC), nitrogen oxides (NOx), and smoke opacity were analysed. It was observed that when CuO nanoparticles were used as additives for the B20 blend, BTE increased significantly by about 1.18%-7.69% and BSEC decreased considerably by about 4.12% 6.76%. In addition, when CuO nanoparticles were added, there were also substantial reductions in CO (2.21% 8.86%). Furthermore, there was a noticeable increase in HC (0.3% 9.78%), CO2 (2.38% 5.97%), and NOx emission levels (1.75% 5.27%) when compared to the B20 blend. However, in comparison to diesel fuel, all the emission levels were lower for all biodiesel blends except for NOx emissions. Overall, it was concluded that CuO nanoparticles could be considered as an appropriate petroleum additive for palm oil biodiesel blends.
