| Abstract: | The strategy of fuzzy PID for fuel pressure control was used to simulate the fuel pressure in the common rail. Using it as the boundary conditions, 3 D CFD flow field of different nozzles geometry was calculated to investigate the influence of the high pressure common rail fuel pressure fluctuations on the flow field in the nozzle and injection. The results can provide more realistic boundary conditions for flow uniformity among holes in the injector and downstream spray, which are very useful for the optimum design of the nozzle structure parameters. |
