摘要
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.
A geometric model of combustion chamber for gasoline engines is proposed on the basis of spherical trigonometry. The model can be used to calculate the flame propagation in the combustion chamber. By using this model, the flame area and burnt volume in relation to the flame front were calculated for the cubic combustion chamber and for the combustion chamber of the CA6102 gasoline engine. The results prove that the model is effective.
