    Calibration of EGR system of ethanol/diesel blend fuel engine

      Graphical Abstract
      • Abstract
    • The calibration of EGR system of ethanol/diesel blend fuel engine DL190-12 was carried out. The control of flow of exhaust gas recirculation was completed with adjusting opening width of EGR valve which was controlled by vacuum. The method of line condition’s calibration for vacuum in EGR valve was proposed. Value engineering principle was applied in the optimization of engine performance test results for calibration of vacuum in EGR valve. The model of engine performance evaluation was established, the evaluation indexes were proposed, and their weights were given. The best vacuum MAP of EGR valve by two-grade evaluation methods was obtained, the results was reasonable and could be used in EGR control.
