The primary objective of this work was to enhance the performance and emission of the computerized variable compression ratio (VCR) diesel engine fuelled with pentanol/Calophyllum inophyllum (CI)/diesel fuel blends. Based on the prerequisite for the current research, response surface methodology (RSM), an optimization technique, was adopted for the process parameters compression ratio (CR), load and fuel blends, and the optimized responses like brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), oxides of nitrogen (NO), carbon monoxide (CO), carbon dioxide (CO), hydrocarbon (HC), and smoke were revealed with the help of Derringer's desirability approach. From the results, it is notified that pentanol-fuelled engine showed better performance and emissions at 17.5 CR, P20C20 (pentanol 20%+Calophyllum inophyllum 20%+diesel 60%) blend and 2.5 bmep (brake mean effective pressure) load conditions. The observed mathematical models and validation experiments show that the VCR diesel engine exhibits maximum efficiency and minimum emissions at the optimized input parameters.
这项工作的主要目的是提高计算机控制可变压缩比（VCR）柴油机在戊醇/桐油（CI）/柴油燃料混合物中的性能和排放。基于当前研究的前提，响应面法（RSM），一种优化技术，被用于压缩比（CR）、负载和燃料混合物等过程参数，借助 Derringer 的适宜性方法揭示了优化响应，如制动热效率（BTE）、制动比油耗（BSFC）、氮氧化物（NO）、一氧化碳（CO）、二氧化碳（CO）、碳氢化合物（HC）和烟雾。结果表明，在 17.5 CR、P20C20（戊醇 20%+桐油 20%+柴油 60%）混合燃料和 2.5 bmep（制动平均有效压力）负载条件下，戊醇燃料发动机表现出更好的性能和排放。观察到的数学模型和验证实验表明，在优化的输入参数下，VCR 柴油机表现出最大的效率和最小的排放。
