摘要: 筛选了多种汽油中的特征组分和不同种类的含氧化合物,利用定容燃烧弹对其自燃特性和火焰传播速度进行了对比研究,从燃烧学的角度为汽油的调合和替代燃料的选择提供了理论依据。由研究结果得出了有意义的结论:呋喃类燃料在低当量比情况下仍能保持较高的火焰传播速度,稀薄燃烧(稀燃)边界条件较宽,是极具潜力的适合稀燃模式的燃料组分。

Abstract: The spontaneous ignition characteristic and flame propagation velocity of several kinds of gasoline were compared by using constant volume combustion bombs, which provided a theoretical basis for gasoline blending and alternative fuel selection from the view of combustion science. It was concluded that furan-based fuels could maintain high flame propagation speed, had a wide dilution boundary at low equivalence ratios, and were potential lean-burn components.

Key words: gasoline, oxygenated biomass, lean-burn, ignition delay, flame propagation
