Performance of diesel engine with high fuel pressure injection is related its emission gas and fuel consumption. In this study, by using 3rd generation piezo-driven injector model, two-stage injection characteristics and effects were analyzed. And numerical model with injection rate and hydraulic pressure about two-stage injection were developed and verified with experimental results.
