摘　　要：针对某型柴油机结构,在原单弹簧喷油器的基础上,设计出一款适用的双弹簧喷油器,并运用软件GT-SUITE进行仿真分析,探讨双弹簧喷油器的喷射特性,最终通过对比分析得出双弹簧喷油器性能的优越性。A suitable double-spring injector is designed on the basis of the original single-spring injector for a certain diesel engine. The injection characteristics of the double-spring injector are investigated by the simulation analysis of the software GT-SUITE. Finally, the superiority of double-spring injector is verified by the comparative analysis.
