| Abstract: | The intake manifold has a great effect on the power,economy and emission of the EFI engine. The layout and configuration of the intake manifold are the main factors affecting the performance of the engine,so optimal design should be proceeded.In this paper,an optimal design method integrating CAD and CFD codes is presented and applied to the intake manifold of EQ49H EFI engine.And the computational models are verified by the experiments.The whole design process shows that the integrated CAD/CFD optimal method is an effective and feasible method for the design of engine intake system. |
