ンジン。A variable nozzle vane is provided on the turbine nozzle of the exhaust turbo supercharger, and an operating mechanism is provided to open and close this variable nozzle, and the variable nozzle is equipped with a variable nozzle vane that responds to changes in engine speed and engine load detected by a rotation speed detector and a load detector. Based on the operation mechanism, the opening degree of the variable nozzle vane is variably operated, and in the low speed rotation range of the engine, the opening degree of the variable nozzle vane is maintained in a narrowed state, and in the high speed rotation range of the engine, the opening degree of the variable nozzle vane is maintained in a narrowed state. In a turbocharged engine that is held in an open state with a wide opening, a delay mechanism is provided that delays a change in engine rotation speed detected by the rotation speed detector by a predetermined period of time and transmits the delayed change to the operating mechanism; A turbocharged engine characterized in that the opening degree of the variable nozzle vane is maintained in a throttled state when the engine suddenly accelerates under no load.
