| Abstract: | The three-dimensional flow field in a combination intake system with tangent intake port and helical intake port of a diesel engine was simulated.The analysis of the 3D flow field revealed the performance of flow and provided strong support for optimizing design. Without changing the figure size of intake port, the ports position had been optimized by means of comparing the steady flow test results. It is consistent with theory analysis of the simulation results that indicated numerical simulation could play an effective role to guide engine port design. |
