| Abstract: | The structural features and design essentials of intake and exhaust ports of m ulti-valve engines were analyzed. The methods for investigations of port perfor m ance, static simulation of flow fields, steady flow experimental evaluation and instantaneous simulation with moving mesh were expounded taking a self-develop ed four-valve 1110 diesel engine and a 486QE gasoline engine as examples. These methods can be applied to the design and evaluation of intake and exhaust ports of multi-valve engines. |
