| Abstract: | Based on the performance analysis of the electron-controlled booster(ECB) of the augment high pressure common-rail system,a new structure booster with 2-position 3-way solenoid valve was designed and its system simulation model was established.The simulation results based on the model indicate that new type ECB can raise augment chamber peak pressure by 15 MPa,reduce the control fuel oil consumption by 35.2% and eliminate the pressure oscillation in the chamber.Realization of adjustable injection rate favor... |
