The design of the intake port is very critical for the intake process and the other operating parameters of internal-combustion engines, and it significantly determines the overall performance of the combustion system. Traditionally, the development of the intake port was a time-consuming process which involved considerable test work and needed solid experience in relevant areas. Combining the long-time practices and understanding on this subject, a parameterized design method for the intake port design was explored by the current research group. Based on the existing three-dimensional computer-aided design software, a parameterized tangential port model was developed with six port structural parameters for establishing the structure of the intake port. In order to build the relationship between the port parameters and the performance, computational fluid dynamics numerical simulation was conducted by considering 11 different tangential ports. The results show that the performances of the tangential port could be controlled by necessary adjustments of the practical boundary conditions and the specified structure parameters. Finally, the technology was applied to the intake port design of a production diesel engine, and this proved that the proposed method can provide not only the optimized port performance but also significant savings for the design time and the working load.
