Abstract A rapid increase in fossil fuel consumption and its environmental degradation create a demand for biodiesels as a replacement of diesel fuel. Water emulsion in base fuel is a suitable pre-processing emission control technique as it can reduces the emissions level with improved engine performance. Based on the motivation, a novel attempt has been made in this present study to evaluate the suitability of LPO and water emulsion as a green fuel for diesel engine. LPO is extracted from lemon fruit rinds using a steam distillation method, and various fuel samples are prepared based on LPO’s volumetric concentration in BD. Emulsion fuel is prepared using sorbitan monolaurate surfactant through mechanical homogenization. The physicochemical properties of sample fuels have been measured based on ASTM standards and their suitability tests are conducted in a single cylinder, four stroke and natural aspirated diesel engine at various BMEP conditions. The experimental results show that LPO promotes the BSFC and BTE by 11% and 16.2% at peak BMEP condition compared to BD, respectively. The emission parameters of LPO such as HC, CO, and smoke are reduced by 46.9%, 57.3%, and 15.9% compared to BD, respectively, whereas the NOx and CO2 emissions are increased by 20.7% and 29.5%. The ICP and NHR values are increased for LPO compared to BD due to longer IDP. LPO10W emulsion fuel further improves the BSFC and BTE by 9.8% and 11.6%, and reduces the HC, CO and NOx emissions by 18.7%, 33.3% and 26% compared to LPO, respectively.

以柠檬皮油和水乳液为燃料的 CI 发动机兼容性测试

摘要 化石燃料消耗的迅速增加及其环境恶化产生了对生物柴油作为柴油燃料替代品的需求。基础燃料中的水乳液是一种合适的预处理排放控制技术,因为它可以降低排放水平并提高发动机性能。基于此动机,本研究进行了一项新尝试,以评估 LPO 和水乳液作为柴油发动机绿色燃料的适用性。使用蒸汽蒸馏法从柠檬果皮中提取 LPO,并根据 LPO 在 BD 中的体积浓度制备各种燃料样品。乳化燃料是使用脱水山梨糖醇单月桂酸酯表面活性剂通过机械均化制备的。样品燃料的理化性质已根据 ASTM 标准进行测量,并在各种 BMEP 条件下在单缸、四冲程和自然吸气柴油发动机中进行了适用性测试。实验结果表明,与 BD 相比,LPO 在峰值 BMEP 条件下分别将 BSFC 和 BTE 提高了 11% 和 16.2%。与BD相比,LPO的HC、CO和烟雾等排放参数分别降低了46.9%、57.3%和15.9%,而NOx和CO2排放量分别增加了20.7%和29.5%。由于更长的 IDP,LPO 的 ICP 和 NHR 值比 BD 增加。与LPO相比,LPO10W乳化燃料的BSFC和BTE进一步提高了9.8%和11.6%,HC、CO和NOx排放量分别降低了18.7%、33.3%和26%。在各种 BMEP 条件下的四冲程和自然吸气柴油发动机。实验结果表明,与 BD 相比,LPO 在峰值 BMEP 条件下分别将 BSFC 和 BTE 提高了 11% 和 16.2%。与BD相比,LPO的HC、CO和烟雾等排放参数分别降低了46.9%、57.3%和15.9%,而NOx和CO2排放量分别增加了20.7%和29.5%。由于更长的 IDP,LPO 的 ICP 和 NHR 值比 BD 增加。与LPO相比,LPO10W乳化燃料的BSFC和BTE进一步提高了9.8%和11.6%,HC、CO和NOx排放量分别降低了18.7%、33.3%和26%。在各种 BMEP 条件下的四冲程和自然吸气柴油发动机。实验结果表明,与 BD 相比,LPO 在峰值 BMEP 条件下分别将 BSFC 和 BTE 提高了 11% 和 16.2%。与BD相比,LPO的HC、CO和烟雾等排放参数分别降低了46.9%、57.3%和15.9%,而NOx和CO2排放量分别增加了20.7%和29.5%。由于更长的 IDP,LPO 的 ICP 和 NHR 值比 BD 增加。与LPO相比,LPO10W乳化燃料的BSFC和BTE进一步提高了9.8%和11.6%,HC、CO和NOx排放量分别降低了18.7%、33.3%和26%。与BD相比,LPO的HC、CO和烟雾等排放参数分别降低了46.9%、57.3%和15.9%,而NOx和CO2排放量分别增加了20.7%和29.5%。由于更长的 IDP,LPO 的 ICP 和 NHR 值比 BD 增加。与LPO相比,LPO10W乳化燃料的BSFC和BTE进一步提高了9.8%和11.6%,HC、CO和NOx排放量分别降低了18.7%、33.3%和26%。与BD相比,LPO的HC、CO和烟雾等排放参数分别降低了46.9%、57.3%和15.9%,而NOx和CO2排放量分别增加了20.7%和29.5%。由于更长的 IDP,LPO 的 ICP 和 NHR 值比 BD 增加。与LPO相比,LPO10W乳化燃料的BSFC和BTE进一步提高了9.8%和11.6%,HC、CO和NOx排放量分别降低了18.7%、33.3%和26%。
