Abstract: The current assessment methods of intake port by adopting discharge coefficient and swirl intensity measurement from a steady-flow test rig is a high-cost and time-consuming process. The three-dimensional flow model was built; flow characteristics and the law of variation in discharge were analysed in this paper. The measurement in the test rig verify the numerical results. The local optimisation and simulation analysis of the intake port were made in this study and reversed flow in the inside of the bending segment was eliminated, which increased the minimum circulation area and lowered the intake resistance. As a result, the flow coefficient of the intake port was greatly increased.
