| 摘 要： | 涡流和流量系数是影响柴油机经济性与排放特性的关键参数,在柴油机设计和改进过程中需要对气道的此两个参数进行测量和评价。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。

| Abstract: | Swirl is a key parameter that directly influences the efficiency and exhaust property of diesel engine,and it must be taken into consideration in designing and development process.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. |

| Keywords: | Swirl ratio Flow coefficient Diesel engine Steady-state test bench |
