摘要
对电控喷射125mL汽油机和乙醇发动机的过量空气系数和点火提前角与排放性能之间的关系进行了试验研究。确定了影响乙醇发动机排放的敏感参数的合理取值范围,为乙醇发动机参数匹配提供了参考依据,并验证了发动机燃烧乙醇燃料可降低NOx的排放浓度。
Effects of excess air ratio φa and ignition advanced angle θ on CO,HC and NOx emissions from a 125 mL gasoline and ethanol engine with electronic fuel injection were studied experimentally.It is proved that ethanol engine emits less NOx than equivalent gasoline engine.Relatively optimal ranges of φa and θ to lower emissions from ethanol engine were proposed which are useful to the parameter matching of ethanol engine.
