The current research work is based on exploring a novel biological fuel source and renewable fuel offered by waste lemon fruit skin. Furthermore, bio-based multi-wall carbon nanotubes (BMWCNTs), emulsion, fossil diesel, and raw lemon peel oil were procured. The single-cylinder diesel engine was evaluated using these potential ingredients in terms of performance, combustion, and emission. Test engine results reveal that the presence of BMWCNT emulsion in the bio-fuel + blend + emulsion blend produced a lower (4.7%) brake thermal efficiency (BTE) and a higher (13.6%) brake-specific energy consumption (BSEC) at peak engine load conditions with diesel. The same test fuel blend possesses an equivalent heat release rate (HRR) and cylinder pressure trends to the diesel fuel blend due to an optimized air/fuel mixture and oxygen supply. Bio-fuel + blend + emulsion achieved step-down reductions of 7.83% carbon monoxide (CO) and 20.68% hydrocarbon (HC) emissions, as well as reductions of 27.7% nitrogen oxide (NO) and 37.3% smoke emissions at peak engine load with diesel.
当前的研究工作基于探索废弃柠檬果皮提供的一种新型生物燃料源和可再生燃料。此外，采购了生物基多壁碳纳米管（BMWCNTs）、乳液、化石柴油和生柠檬皮油。使用这些潜在成分对单缸柴油发动机的性能、燃烧和排放进行了评估。试验发动机结果表明，在生物燃料+混合燃料+乳液混合燃料中存在BMWCNT乳液时，在发动机满负荷工况下，与柴油相比，制动热效率（BTE）降低了4.7%，制动比能耗（BSEC）提高了13.6%。由于优化了空气/燃料混合物和氧气供应，相同的试验燃料混合物具有与柴油燃料混合物相当的热释放率（HRR）和气缸压力趋势。生物燃料+混合燃料+乳液在发动机满负荷工况下与柴油相比，一氧化碳（CO）排放量降低了7.83%，碳氢化合物（HC）排放量降低了20.68%，氮氧化物（NO）排放量降低了27.7%，烟雾排放量降低了37.3%。
