| 5. | Most of present study of 3 - d revolve intake is mainly on the self - intake state . that is to study the air flow in different valve lift , but there is no relative report on the turbo operating conditions in our country
在气道稳态试验时，当进气压力增加到大于20 . 4kpa后，真空泵就不能正常的工作而使得吸气压力达不到试验的要求。 |
| 6. | To measure the concerned parameter at production line , a highly automatic steady - state test bench based on the old version is presented in this paper , on which the valve lift and test pressure are all computer - controlled
本文在原气道试验台基础上，设计了一套自动化程度较高的气道稳态试验台，可以对气门升程和试验压力进行自动调节，适用于生产线上使用。 |
| 7. | Perform fluid simulation on the helical intake port - valve - cylinder flow field under the condition of steady flow testing rig . the results under different valve lifts are gained . the research of this paper is practically useful
对所建立的模型进行了稳流实验台条件下气道-气门-气缸内的三维定常流动模拟计算，计算了不同气门升程下气道的性能评价参数。 |
| 8. | The technical line of the thesis is as follows : formula of quantity of fuel injection is got by studying relation of quantity of fuel injection and needle valve lift , time of fuel injection , rotation speed and pressure , and quantity of fuel injection is displayed
