Abstract:The optimization method of the high pressure common rail diesel engine injection system parameters was put forward based on approximate model. First the spray and combustion model in CFD software were verified and validated through the test data, and central composite method was used to design the experimental matrix, and the simulation calculation experiment was carried out with CFD, thus the response surface approximate model was established. Finally the global optimization was done with the approximate model, and the optimal parameters of injection system were obtained. |
