The study presented the blends of waste vegetable oil with kerosene (K-WVO) as diesel substitutes. Three K-WVO blends containing 0.20, 0.35, and 0.50 fraction of WVO in kerosene are comprehensively analyzed for combustion, performance, emissions, economics, and environmental impacts. The engine performance and combustion profiles of the blends were comparable to that of diesel. The blend containing 0.20 fraction as WVO demonstrated better fuel consumption and combustion efficiency than diesel. K-WVO blends showed lower specific carbon monoxide emissions but higher unburnt hydrocarbon emissions relative to diesel. The emission of nitrogen oxide was similar for the blend fuels and diesel. The blends were found to be much economic than diesel. A 52–61% reduction in running cost can be achieved by substituting diesel with a K-WVO blend. The blends with higher WVO fraction are found to be more economic. The use of K-WVO blends can be expected to lower the global warming potential by 19.6–21% compared to diesel fuel. Largely, the blend fuels were found to have lower environmental impacts compared to diesel. The study showed that the benefits associated with a blend depend on blend composition. The blend with a lower WVO content can have better engine performance and emission characteristics, but blend with a higher WVO has more economic and environmental benefits. Thus, the comprehensive assessment presented in the study can be used as a guide toward defining the proper WVO-kerosene blend composition based on the proposed objective.

综合评估可持续的低成本废植物油基混合物作为柴油的替代品

该研究提出了废植物油与煤油(K-WVO)的混合物作为柴油的替代品。全面分析了煤油中WVO含量分别为0.20、0.35和0.50的三种K-WVO共混物的燃烧,性能,排放,经济和环境影响。混合物的发动机性能和燃烧曲线与柴油相当。含有0.20馏分的WVO的混合燃料比柴油具有更好的燃料消耗和燃烧效率。与柴油相比,K-WVO混合物的一氧化碳排放量较低,但未燃烧的碳氢化合物排放量较高。混合燃料和柴油的氮氧化物排放量相似。人们发现这种混合物比柴油经济得多。用K-WVO混合物代替柴油可以使运行成本降低52-61%。发现具有较高WVO分数的共混物更经济。与柴油相比,使用K-WVO混合燃料可将全球变暖潜能降低19.6-21%。在很大程度上,发现混合燃料与柴油相比对环境的影响较小。研究表明,与共混物有关的益处取决于共混物的组成。WVO含量较低的混合物可以具有更好的发动机性能和排放特性,但是WVO含量较高的混合物可以带来更多的经济和环境效益。因此,研究中提出的综合评估可以作为指导,以根据提出的目标确定适当的WVO-煤油共混物组成。与柴油相比,为6–21%。在很大程度上,发现混合燃料与柴油相比对环境的影响较小。研究表明,与共混物有关的益处取决于共混物的组成。WVO含量较低的混合物可以具有更好的发动机性能和排放特性,但是WVO含量较高的混合物可以带来更多的经济和环境效益。因此,研究中提出的综合评估可以作为指导,以根据提出的目标确定适当的WVO-煤油共混物组成。与柴油相比,为6–21%。在很大程度上,发现混合燃料与柴油相比对环境的影响较小。研究表明,与共混物有关的益处取决于共混物的组成。WVO含量较低的混合物可以具有更好的发动机性能和排放特性,但是WVO含量较高的混合物可以带来更多的经济和环境效益。因此,研究中提出的综合评估可以作为指导,以根据提出的目标确定适当的WVO-煤油共混物组成。但与更高的WVO混合可带来更多的经济和环境效益。因此,研究中提出的综合评估可以作为指导,以根据提出的目标确定适当的WVO-煤油共混物组成。但与更高的WVO混合可带来更多的经济和环境效益。因此,研究中提出的综合评估可以作为指导,以根据提出的目标确定适当的WVO-煤油共混物组成。
