摘要
作者用自行开发的软件对在油泵试验台上测得的喷油压力、针阀升程信号进行了数据采集和计算,在试验的基础上提出了分析喷油过程的四个判据。
The authors carry out data collection and calculation for fuel injection pressure and needle valve lift signals measured on the fuel pump test bed by using self-developed software.On the basis of experiments,four criteria for analysing fuel injection process are proposed and the comparison of performances between AU and NU type fuel outlet valves is made.
