The ignition delay period is controlled by the fuel injection advance angle which is an important parameter. If the advance angle of injection is adjusted earlier, the density of the combustion chamber is small and its temperature is low, when the fuel is injected into the combustion chamber. So it needs long time to atomization.

喷油提前角是影响燃烧滞燃期的重要参数，喷油提前角的大的工况，燃油喷入燃烧室时缸内空气的密度小，温度低，燃油雾化所需时间长，sauter平均直径大，油滴汽化的表面积越小，所以油束雾化效果不好。
