The utilization of plastic in day to day life is ever-increasing and has generated a large amount of plastic garbage that needs proper disposal to save the environment from harmful pollution. The plastic waste management becomes a pressing concern in the present scenario in developing countries like India. This research article evaluates the potential of synthetic fuel (SF) derived from waste plastics collected from the local shops. In this current investigation, the SF blends are tested in a direct injection diesel engine to analyze the performance and emission characteristics of the engine. Three different blends were made namely SF20, SF40, and SF60 on a volumetric basis and the tests were carried out. From the experimental results, it was found that brake thermal efficiency (BTE) of the fuel blends was reduced as compared with neat diesel operation regardless of loads whereas SF20 showed a similar trend as that of diesel operation. The analysis of the emission characteristics revealed that the SF20 blends reduced dangerous smoke and carbon monoxide emission as compared with other test fuels. From the overall results, SF20 showed superior performance and emission aspects as compared with other SF blends whereas the engine operated smoothly up to 60% of SF blending at all loading conditions.
日常生活中塑料的使用量与日俱增，产生了大量的塑料垃圾，需要妥善处理，以防止环境受到有害污染。在印度等发展中国家，塑料废物管理成为当前迫切需要关注的问题。 本研究文章评估了从当地商店收集的废塑料中提取的合成燃料 (SF) 的潜力。在当前的研究中，将 SF 混合物在直喷式柴油机中进行测试，以分析发动机的性能和排放特性。基于体积分别制备了三种不同的混合物，即 SF20、SF40 和 SF60，并进行了测试。从实验结果可以看出，与使用纯柴油相比，无论负荷如何，燃料混合物的制动热效率 (BTE) 都会降低，而 SF20 表现出与柴油操作相似的趋势。排放特性分析表明，与其他测试燃料相比，SF20 混合物减少了危险的烟雾和一氧化碳排放。从整体结果来看，与其他 SF 混合物相比，SF20 显示出更好的性能和排放方面的优势，而在所有负载条件下，发动机在高达 60%的 SF 混合比下都能平稳运行。
