置。 A boost pressure detector that detects the boost pressure in the air supply passage of the engine body, a turbine inlet pressure detector that detects the turbine inlet pressure of the supercharger installed in the exhaust passage of the engine body, and turning on and off the exhaust brake. An exhaust brake switch that detects the state is connected, and when the pressure difference between the turbine inlet pressure and the boost pressure is larger than a preset set pressure while the exhaust brake is held in the OFF state, the supercharging is performed. A controller is provided to forcibly open the waste gate valve upon determining that the turbocharger is in a malfunction state, and at the time when the controller determines that the turbocharger is in a malfunction state, the turbocharger is in a malfunction state. A control device for a waste gate valve, characterized in that it is provided with a display section for displaying information.
