The design of the intake port plays a critical role in the development of modern internal combustion (IC) engines. The traditional method of the intake port design is a time-consuming process including a huge amount of tests and the production of core box. Compared with the traditional methods, parametric approach attracts increasing attentions by virtue of its high-efficiency, traceability, and flexibility. Based on a tangential port model created by a three-dimensional (3D) computer aided design (cad) software, a new tangential port can be quickly generated with different sets of structure parameters, then computational fluid dynamics (CFD) was employed to explore the influence of structure parameters on the intake port performance. The results show that the flow capacity and the large-scale vortex intensity change regularly with the variations of structure parameters. Finally, the parametric approach was employed to design the intake port of a production four-valve direct-injection (DI) gasoline engine, and the good applicability this approach is well illustrated.
