| Abstract: | Flow characteristics of intake port in 4 different valve lift are analyzed by using AVL FIRE software, which reveals flow characteristics of certain engine intake port and in-cylinder. Gas flow, turbulence energy, speed isopleth map, ratio of flow coefficient and swirl rate are achieved, which show intuitively that flow characteristics of port and in-cylinder during intake and supply methods and basis for performance optimization, evaluation and redesign of intake port. |
