The experimental investigation has been carried out on the diesel engine using Chlorella vulgaris algal biodiesel as blends with neat diesel. Two input parameters, such as load and fuel and four reaction parameters such as hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), and smoke, were used for the emissions on the engine. The experimental results show that there's been less pollution from using algae oil blend in the diesel engine. It is employed to find the optimum level for multi-objective prediction carried out for CO, HC, NOx, and smoke. The outcomes after grey relational analysis (GRA) were tested using the response surface methodology (RSM), wherein the optimal combination has been found out using a particular behaviour.

柴油机中小球藻生物柴油的使用优化

已经使用寻常小球藻藻类生物柴油与纯柴油的混合物对柴油发动机进行了实验研究。发动机的排放使用了两个输入参数，例如负载和燃料，以及四个反应参数，例如碳氢化合物（HC），一氧化碳（CO），氮氧化物（NOx）和烟气。实验结果表明，在柴油发动机中使用海藻油混合物可以减少污染。它用于找到针对CO，HC，NOx和烟气进行多目标预测的最佳水平。使用响应面方法（RSM）对灰色关联分析（GRA）之后的结果进行了测试，其中使用特定的行为找到了最佳组合。
