| Abstract: | A new collecting and analyzing system was developed for EUP based on Advantech PCI-1712 high speed multifunction card. Injection pressures, drive torque for EUP and low pressure of fuel were collected and filtered, and the peak injection pressure, injection timing, peak torque value and their differences among 6 cylinders were calculated and achieved for the analysis of an EUP assembly. The EUP assembly was checked whether it had defect or not, and those elements that had defects were displayed. This system has been used successfully in testing the EUP assembly at Machinery Group Co. Ltd. |
