摘要
在稳流气道试验台上，用热线风速仪测量了切向气道进气门出口速度和紊流强度分布。发现气门升程和气门周围燃烧室结构对速度和紊流强度分布影响较大；速度、紊流强度不仅沿气门头周围变化，而且还沿气门轴线方向变化。

Results showed that velocity and turbulence intensity profiles were strongly dependent on valve lift and surrounding geometry, velocity and turbulence intensity were changed not only around the valve periphery but also along the direction of valve axis.
