dc.description.abstract	As the awareness of the environmental protection and energy conservation, a more restricted rule is proposed on engine performance, e.g. high power output, fuel economy and low pollution. It is very important to understand the spray atomization mechanism and the factors which have effects on the characteristics spray and its regulation. The combination of LES (Large eddy simulation) and the VOF method by using open source CFD software OpenFoam in Linux system is used to imitate umbrella morphology on the oil spray and fracture mechanism in the primary atomization stage. The radial and axial velocity, pressure and droplet distribution are obtained by present method and some meaningful results are concluded. Finally, the influence of the air dynamics on the fuel primary breakup and the effects of grid sizes for LES are analyzed.	en_ZA
