为设计多气门汽油机强滚流进气道，作者对所设计的几种滚流进气道模型在稳流试验台上进行了性能测试。结果指明了强滚流进气道对结构的要求，揭示了上大下小的喉口截面形状的进气道可得到较强的滚流强度，但难以提高综合进气性能指标，并证实用滚流进气道与作者研制的导流型副气道的组合进气方案可实现提高滚流强度而不牺牲进气流量系数。
In order to design a strong tumble inlet into a multi-valve gasoline engine, the authors tested the performance of several tumble inlet models designed on a steady flow test rig. The results indicate that the structure of the strong tundish inlet must meet the requirements of the structure. It is found that the intake trough with big throat and small throat cross section can get stronger tumble strength, but it is difficult to improve the performance of the integrated inlet gas. The combination of the tundish inlet duct and the diversion-type accessory air duct developed by the author can improve the tumble strength without sacrificing the intake air flow coefficient.
