Abstract
This paper realized the 3-dimension model for helical intake port and simulated the different kinds of position deviations by the application of reverse engineering. The three-dimensional flow field in port-cylinder was numerically simulated by the use of CFD software FIRE to verify how the position deviations affect the performance of the helical intake port. The result shows that the slanting and translational position deviations have the marked effect on the swirl ratio of the helical intake port and the strict control of production precision is needed.
