| 摘 要： | 在稳流气道试验台上用叶片风速仪测量了4气门发动机单气门工作时缸内的滚流运动。确定了最大滚流矢量的位置;用热线风速仪研究了罐内滚流的形成过程,发现滚流轴线与水平面的夹角随气门升程的增大而增大。此时形成的“滚流”并非纯粹的滚流,而是斜轴涡流。

| Abstract: | The in cylinder tumble motion of a 4 valve engine with one inlet valve opening was studied on steady flow rig with vane anemometer and the position of maximum tumble vector was found;The forming process of in cylinder tumble was studied with Hot Wire Anemometer.It is found that the angle between tumble axis and horizontal plane increases with valve lift.The "tumble" is not a pure tumble,but is a inclined swirl. |
