A turbocharger turbine is disposed in an exhaust passage connected to the engine, and a blower interlocked with the turbine is disposed in an intake passage connected to the engine, and the blower is disposed on the upstream side of the turbine in the exhaust passage. A throttle valve is provided to increase or decrease the cross-sectional area of the blowing flow path to the turbine, and a boost pressure control device is provided to control the boost pressure by controlling the opening degree of the throttle valve in response to the amount of operation of the accelerator. In the engine control device, the boost pressure control device is configured to control the opening degree of the throttle valve in a range equal to or greater than the minimum opening degree set in accordance with the engine rotation speed. A control device for an engine equipped with a supercharger.
