摘要

摘要当研究了两种或两种以上的混合物组合和一种或多种工艺因素时,基于混合物和工艺设计的组合优化工具显示出精确的预测和优化结果。因此,本研究采用CMPD法对预混20%芒果籽甲酯与80%柴油(MB20)的混合组分进行了优化;2-丙醇和1-己醇组分用可变负荷的工艺因素进行了优化。工艺因素负荷以25%的间隔从0到100%变化,而在每种情况下,酒精的量不允许超过15%(按体积计)。所设计的CMPD模型将CO、CO2、O2、HC和NOx等排放参数优化到最低水平,以使测试发动机产生最大的制动热效率(BTE)。所开发的优化模型实现了BTE的最大回归值(R2)0.9826,而CO获得了最低值(即0.9254 R2)。然而,该模型将BTE、BSFC、CO、CO2、O2、NOx和HC值优化为24.31%、0.452 千克/千瓦时,0.133%,3.397%,15.896%,283.268 ppm和17.879 ppm,可取值为0.884。这表明最佳燃料组合为80%的MB20、5%的2-丙醇和15%的1-己醇,负载为76.086%。

Optimization of biodiesel/2-propanol/1-hexanol blends based on diesel engine performance using combined mixture-process design (CMPD)
Abstract The combined mixture and process design (CMPD)-based optimization tool showed precise prediction and optimized results when there were two or more mixture combinations and one or more process factors investigated. Therefore, in this study, the CMPD method was employed to optimize the mixture components of premixed 20% mango seed methyl ester mixed with 80% diesel (MB20); 2-propanol and 1-hexanol components were optimized with process factor of variable loads. The process factor load was varied from 0 to 100% at 25% intervals, whereas the amount of alcohol was not permitted to exceed 15% by volume in each case. The designed CMPD model optimized the emission parameters such as CO, CO2, O2, HC and NOx to their minimum levels to produce maximum brake thermal efficiency (BTE) from the test engine. The developed optimization model achieved a maximum regression value (R2) of 0.9826 for BTE while CO attained the lowest value (i.e. 0.9254 R2). However, the model optimized BTE, BSFC, CO, CO2, O2, NOx and HC values as 24.31%, 0.452 kg/kw.h, 0.133%, 3.397%, 15.896%, 283.268 ppm and 17.879 ppm, respectively, with the desirability of 0.884. This suggests the optimum fuel combination is 80% MB20, 5% 2-propanol, and 15% 1-hexanol with a 76.086% load.
