| 摘 要： | 以一维进排气管流动和缸内零维燃烧模型理论为基础,建立了点燃甲醇发动机的工作过程计算模型.通过计算结果与实验数据的对比,对模型的精度和可靠性进行了验证.依据建立的模型,针对几种不同的进气迟闭角(IVC)和排气提前角(EVO)分别在3个工况下进行发动机的性能参数模拟计算,由此各自初步筛选出三组角度,最后用排列组合方法进行再次优化分析,确定了一组最佳的进气迟闭角、排气提前角和气门重叠角.

| Abstract: | The simulation model of spark ignition methanol engine was established based on one-dimensional intake and exhaust pipe flow theory and in-cylinder zero-dimensional combustion model theory.Measured data was proved to be consistent with the calculation data.The performance simulation of the methanol engine based on three operate conditions were studied,and three groups of valve timing(IVC and EVO) is optimized firstly.Finally,the optimal valve timing was determined by interactive method through the compariso... |
