The ignition process of single droplet of blended multicomponent fuels in hot oxygenated ambience is studied in this paper. Ignition delay time is predicted with considing the heating process of droplet, and agree well with the experimelltal data. The results show that the ignition of mu1ticomponent fuels is controlled by the component which is easy to be volatiled and it is favor for ignition to add a small amount of such fuel with lower boiling poillt.
