In this paper, A 3-D model of helical intake port- valve- cylinder is built, and flow characteristic of helical intake port is carried out; the accuracy of the CFD (Computational Fluid Dynamics) simulation is verified by steady flow test rig and the detailed interior flow field is obtained. The results indicate: the numerical simulation results show great consistency with the test values; the calculation of the high valve lift is more precise than that of the low one and feasibility evaluating intake port by CFD is verified.
