The study employed an Artificial Neural Network (ANN) to predict the performance and emissions of a single-cylinder SI engine using blends of Gasoline, Ethanol, and Methanol (GEM) ranging from E10 to E50 equivalence, achieving less than 5% error compared to experimental values. Furthermore, Response Surface Methodology (RSM) was utilized to optimize the engine's performance, identifying the optimal operating conditions of 2992.9 rpm engine speed and an E20-equivalent GEM blend. Under these conditions, the engine exhibited a brake thermal efficiency (B_The) of 34.63%, a brake specific fuel consumption (BSFC) of 243.7 g/kW-hr, and minimal emissions of 1.5% CO, 108.13 ppm HC, and 1211.8 ppm NO, with an overall desirability of 0.820, indicating a highly favorable combination of performance and emissions characteristics.
该研究采用人工神经网络(ANN)来预测单缸火花点火发动机使用从E10到E50当量的汽油、乙醇和甲醇混合燃料(GEM)时的性能和排放,与实验值相比误差小于5%。此外,利用响应面方法(RSM)优化发动机性能,确定了发动机转速为2992.9转/分钟和E20当量GEM混合燃料的最佳运行条件。在这些条件下,发动机的制动热效率(B_The)为34.63%,制动比油耗(BSFC)为243.7克/千瓦·时,一氧化碳排放最低为1.5%,碳氢化合物排放为108.13 ppm,氮氧化物排放为1211.8 ppm,综合可取性为0.820,表明性能和排放特性的组合非常理想。
