The primary focus of this study is the validation of composite additives with the help of additional optimization methods and the analysis of its effect on the combustion characteristics of compression ignition (CI) engines. Previous work on the identification of the correct multi additive combination by Taguchi and the TOPSIS optimization method has shown substantial improvements in the performance and emission characteristics of CI engines. The same work was extended using the GRA Optimization method with the Multi-Criteria Decision-Making (MCDM) optimization technique known as the Analytic Hierarchy Process (AHP) to validate the optimization results from the previous optimization work. Remarkably, all optimization methods yielded consistent results, pointing to the superiority of the composite additive sample 'D8EH6E4 hence supporting the outcome of previous work. Subsequent testing and comparison of this novel composite additive with baseline diesel fuel for combustion characteristics analysis demonstrated notable improvements in combustion parameters, including a 25 % reduction in the rate of pressure rise, an 18 % decrease in net heat release rate, and a 6 % decrease in mean gas temperature.
本研究的主要重点是借助额外的优化方法验证复合添加剂，并分析其对压燃式（CI）发动机燃烧特性的影响。先前通过田口方法和理想解排序法（TOPSIS）确定正确的多添加剂组合的工作表明，CI发动机的性能和排放特性有了显著改善。使用灰色关联分析（GRA）优化方法和称为层次分析法（AHP）的多准则决策（MCDM）优化技术扩展了相同的工作，以验证先前优化工作的优化结果。值得注意的是，所有优化方法都产生了一致的结果，表明复合添加剂样品“D8EH6E4”的优越性，从而支持了先前工作的结果。随后将这种新型复合添加剂与基准柴油进行燃烧特性分析的测试和比较表明，燃烧参数有了显著改善，包括压力上升速率降低25%、净热释放速率降低18%和平均气体温度降低6%。
