PROBLEM TO BE SOLVED: To provide a supercharging system capable of disabling an air machine without using a clutch.SOLUTION: The supercharging system includes an assist turbine 26 mechanically connected to a turbocompressor 22 as a body of rotation and adapted to be rotated integrally with the turbocompressor 22, and a mechanism for communicating an inlet out of the inlet and an outlet of the assist turbine 26, where a pressure rises with the rotation of the assist turbine 26, with an intake passage 14 as a low pressure part, and closing the outlet where a pressure lowers with the rotation of the assist turbine 26, to disable the assist turbine 26 while keeping the assist turbine 26 connected to the turbocompressor 22. 【課題】クラッチを用いることなく、空気機械を無効化できる過給システムを提供する。【解決手段】過給システムは、回転体であるターボコンプレッサ２２に機械的に連結されて当該ターボコンプレッサ２２と一体となって回転するアシストタービン２６と、前記アシストタービン２６の入口および出口のうち、前記アシストタービン２６の回転に伴い圧力上昇する入口を低圧部である吸気通路１４に連通し、前記アシストタービン２６の回転に伴い圧力低下する出口を閉鎖することで、前記アシストタービン２６と前記ターボコンプレッサ２２との連結を維持したまま前記アシストタービン２６を無効化する機構と、を備える。【選択図】図１
