様にしたことを特徴とする過給圧制御装置。 The supercharging pressure of the exhaust turbo supercharger is taken out as a signal pressure, this signal pressure is adjusted according to the engine exhaust pressure using a modulator with an air bleed port, and the adjusted signal pressure is sent to the pressure chamber of the wastegate valve actuator. In a supercharging pressure control device for an exhaust turbo supercharger that controls the opening degree of a waste gate valve according to the applied signal pressure, the opening area of the air bleed port of the modulator is adjusted according to the atmospheric pressure. A supercharging pressure control device characterized by being provided with a variable altitude compensation mechanism and increasing supercharging pressure in response to a decrease in atmospheric pressure.
