摘　　要：应用FIRE软件对高强化柴油机模拟仿真,结合试验研究分析了喷油压力和油束夹角对高强化柴油机性能的影响,讨论了喷油压力和涡流比的匹配关系。经过实验研究得出:喷射压力对高强化柴油机的动力性影响很大;高压喷射压力、小孔径喷嘴和低涡流三者之间相互匹配,可获得好的发动机性能;当油束夹角为160°时,油气混合最均匀,燃烧状况最佳。The application of FIRE software in Highly Intensified Diesel engine simulation,combining with the experiment analysis of the injection pressure and spray angle on diesel engine performance,discusses the injection pressure and the swirl ratio matching relationship.It show that： injection pressure is great impact on diesel engine power;high injection pressure,small aperture nozzle,low vortex flow between mutual matching,can obtain good engine performance;when the spray angle of 160 degrees,the most homogeneous mixing of oil and gas,combustion condition is best.
