エンジンの制御装置。[Scope of claim for utility model registration] An exhaust turbo supercharger installed across the intake and exhaust systems of an engine, and a blower of the supercharger that rotates when the operating state of the engine reaches a predetermined range. supercharging pressure switching means for increasing the set maximum supercharging pressure by a predetermined pressure; A basic injection amount of fuel is calculated from the rotation signal and fuel is injected and supplied from the injection valve in synchronization with the engine cycle, and when the set maximum boost pressure is switched to the high pressure side by the boost pressure switching means. A control device for an engine with an exhaust turbo supercharger, comprising: a control unit that injects and supplies fuel corresponding to the increase in amount at the time of switching the supercharging pressure from the injection valve in synchronization with the switching.
