本文利用球面三角学的基本原理,建立了一个适用于各种汽油机燃烧室的几何计算模型,可以精确地计算球面火焰在缸盖凹坑中的传播过程.从立方体燃烧室中火焰传播过程的计算,证实了模型的有效性,并利用该计算模型计算了C A6102汽油机燃烧室内火焰传播过程中火焰面积、已燃区容积随火焰传播距离的变化关系.
In this paper, based on the basic principle of spherical trigonometry, a geometric calculation model suitable for various gasoline engine combustion chambers is established, which can precisely calculate the propagation of spherical flame in the cylinder head pit.From the calculation of flame propagation in a cubic combustion chamber , The validity of the model is verified. Based on this calculation model, the change of the flame area and the volume of the burned zone with the propagation distance of flame in the flame propagation of C A6102 gasoline engine combustion chamber are calculated.
