Numerical simulation models of high pressure common rail fuel system were established, the influences of nozzle hole diameter and nozzle hole number on injection rate were studied by means of these models. The research results show that software simulation technology is an effective method for simulation calculation and optimization design for high pressure common rail fuel system(HPCRFS) and comparison between simulation data and experiment data approved the accuracy of simulation models, and the injection rate curve still increases before the end of injection when the nozzle hole diameter is bigger, this kind of injection rate accords with ideal injection law.
