| 摘 要： | 测量模拟气缸内的涡流转速有叶片风速仪和动量计2种方法。利用2气门6110柴油机进气道石膏芯盒进行了试验研究。在使用叶片式风速仪测量模拟气缸内的涡流转速时,分析叶片形状、安置位置可能带来的影响;在一般使用的“定压差法”稳流试验中,从气体流动满足完全发展湍流状态的理论出发,分析了确定模拟气缸内压差值的估算公式。

| Abstract: | Two measuring methods,the blade type anemogr aph and momentum gauge,can be used to simulate the turbulence rotating speed in cylineder.The tests and researches are performed by using intake port plaster core box of2-valve Model6110diesel engine.When the blade type anemograph is used to measure and simulate the turbulence speed,the effect involved possib ly by the blade shape and installation position is tested.In stable flow test c onducted generally by"Constant pressure difference method",according to the theory of gas flow to meet fully turbulence status,the estimation formula of de termining the pressure difference value simulation in cylinder is analyzed. |
