| Abstract: | To develop the fuel pump of a high-pressure common rail fuel injection system, the seal performance of it is one of the most important things influencing working performance of the system. In this research, on the basis of calculating and analyzing the leakage of the high-pressure fuel pump, some seal measures are studied to decrease the fuel leakage of the pump and improve the fuel injection pressure to a large extent. With this research, we can also provide the theoretical basis and applying technology for developing the high-pressure common rail fuel system according to our local situations and getting the self-determinate property right. |
