| Abstract: | High pressure common rail fuel injection system was established by using simulation software GT-suit. The pressure fluctuation and mean pressure fluctuation in a high pressure common rall system as well as injection pressure fluctuation were impact of these fluctuations on the fuel injection rate simulation data that fuel injection system stability was and length-diameter radio is 16. analyzed under different length-diameter ratios. The was further analyzed. It resulted from comparing the optimal when the common rail pipe length is 310 mm |
