Abstract

Present research deals with crude oil production from water hyacinth biomass and its biodiesel preparation. Alcohol additive n‐pentanol is mixed with biodiesel and diesel blends to identify their effects on diesel engine performance and emission parameters experimentally. Water hyacinth oil (WHO) is produced through Soxhlet extraction technique, and its biodiesel is prepared by transesterification. n‐pentanol is mixed through magnetic stirring in biodiesel‐diesel blends to improve their combustion quality and efficiency. Prepared fuel blends properties are examined as per ASTM standards. Experimental results reveal that, BSFC and BTE are evaluated as 0.26 kg/kW‐h and 29.5%, respectively, with HC emissions as 29 ppm, CO emissions as 0.28 vol%, NOx emissions as 330 ppm and CO2 emissions as 2.21 vol% for WHB20D75P5 fuel at maximum load. The comparison of D100 and WHB20D80 with respect to WHB20D75P5 reveals 3.27% reduction and 7.27% improvement in BTE, respectively. Both HC and CO are reduced by 14.70% and 22.22% for WHB20D75P5 fuel compared to diesel. NOx and CO2 emissions are increased by 6.79% and 12.75% for WHB20D75P5 fuel compared to diesel. Overall, WHB20D75P5 fuel is the best performer.

正戊醇与新型水葫芦生物柴油-柴油三元混合物对柴油发动机性能和排放特性的影响

本研究涉及从布袋莲生物质中提取原油并制备生物柴油。酒精添加剂正戊醇与生物柴油和柴油混合物混合，通过实验确定其对柴油发动机性能和排放参数的影响。通过磁力搅拌将正戊醇混入生物柴油-柴油混合物中，以提高其燃烧质量和效率。根据 ASTM 标准对制备的混合燃料性能进行了检测。实验结果表明，WHB20D75P5 燃料在最大负荷下的 BSFC 和 BTE 分别为 0.26 kg/kW-h 和 29.5%，HC 排放量为 29 ppm，CO 排放量为 0.28 vol%，NOx 排放量为 330 ppm，CO2 排放量为 2.21 vol%。与 WHB20D75P5 相比，D100 和 WHB20D80 的 BTE 分别降低了 3.27% 和 7.27%。与柴油相比，WHB20D75P5 燃料的 HC 和 CO 分别减少了 14.70% 和 22.22%。与柴油相比，WHB20D75P5 燃料的 NOx 和 CO2 排放量分别增加了 6.79% 和 12.75%。总体而言，WHB20D75P5 燃料的性能最佳。
