可持续利用废食用油(WCO)作为化石燃料的替代品,由于其具有带来巨大环境和经济效益的潜力,因此受到了广泛关注。本研究试图探索将氧化铝纳米颗粒(AONP)加入WCO对排放的影响,燃烧特性,以及单缸压燃式(CI)发动机的整体性能。对常规商业柴油燃料和纯WCO进行了比较分析,以及WCO与25ppm的AONP的不同混合物,50ppm,和75ppm浓度。实验结果表明,制动热效率(BTE)显着提高,与纯WCO相比,在WCO+75AONP燃料混合物中观察到13.2%的增加。由WCO纳米颗粒共混物作为燃料的发动机显示出显著增加的缸内压力和热释放速率。此外,这些共混物表现出一氧化碳(CO)的大幅减少,碳氢化合物(HC),烟尘排放量减少了44%,31%,48%,分别,与纯WCO相比,氮氧化物(NO)排放量增加了7%。在评估的燃料混合物中,WCO+75AONP混合物表现出更高的发动机性能。这项研究强调了氧化铝纳米颗粒增强的WCO混合物作为可持续能源解决方案的可行和对环境负责的选择的潜力。然而,必须解决生产成本和长期燃料稳定性等挑战,以将纳米燃料确立为经济上可行的替代品。
The sustainable utilization of waste cooking oil (WCO) as an alternative to fossil fuels has gained considerable attention due to its potential for delivering substantial environmental and economic benefits. This research attempts to explore the impact of incorporating aluminum oxide nanoparticles (AONP) into WCO on the emissions, combustion characteristics, and overall performance of a single-cylinder compression ignition (CI) engine. Comparative analyses were conducted against conventional commercial diesel fuel and pure WCO, as well as varying blends of WCO with AONP at 25 ppm, 50 ppm, and 75 ppm concentrations. The experimental results demonstrate a notable enhancement in brake thermal efficiency (BTE), with a 13.2% increase observed in the WCO + 75 AONP fuel blend compared to neat WCO. Engines fueled by WCO nanoparticle blends showed significant augmentation in-cylinder pressure and heat release rates. Furthermore, these blends exhibited a substantial reduction in carbon monoxide (CO), hydrocarbons (HC), and soot emissions by 44%, 31%, and 48%, respectively, while nitrogen oxide (NO) emissions increased by 7% compared to neat WCO. Among the assessed fuel mixtures, the WCO + 75 AONP blend demonstrated higher engine performance. This study underscores the potential of aluminum oxide nanoparticle-enhanced WCO blends as viable and environmentally responsible options for sustainable energy solutions. However, challenges such as production costs and long-term fuel stability must be addressed to establish nano-fuels as financially viable alternatives.
