The validity of the method for numerically predicting the three-dimensional unsteady flow characteristics in the intake port has been examined by comparing the numerical results with the experimental ones under steady conditions. Although the data for the comparison are not sufficient, it seems that the calculation has simulated comparatively well the general characteristics of the flow at the intake valve outlet. From the comparison between the swirl ratio calculated from the flow characteristics at the valve outlet and the swirl ratio calculated from the flow characteristics at the valve outlet. Furthermore, an investigation has been made into the effect of the helical port configuration on the induction swirl intensity and the volumetric efficiency. The effect of the configuration of the valve head and helical part both on the swirl intensity and on the volumetric efficiency has been demonstrated with regard to the helical port.
