| 摘 要： | 在1台进气道多点电喷EQ491i汽油机上,采用AVL傅里叶变换红外光谱多组分分析仪SESAM-FTIR测量了燃用低比例甲醇汽油的排放成分。使用发动机循环模拟软件Boost耦合化学动力学软件Chemkin,建立了甲醇汽油发动机循环计算模型并用试验结果进行标定,模拟了甲醇汽油发动机中的常规排放NOx和非常规排放甲醛的生成情况。模拟结果表明,在相同工况条件下,随着甲醇比例的增大,甲醛排放基本呈线性增长。发动机负荷对甲醛排放影响不大,NOx排放主要受空燃比和燃烧温度影响。

| Abstract: | Based on an inlet port multi-point electronic injection EQ491i gasoline engine,the emissions of gasoline and methanol-gasoline fuel were measured with AVL SESAM-FTIR(Fourier transform infrared spectroscopy) multi-component analyzer.Coupling Boost engine cycle simulation software with Chemkin chemical kinetic software,the calculated model of methanol-gasoline engine cycle was established and calibrated with the experimental results.With the model,the NOx and formaldehyde emissions were simulated.The results ... |
