の排気絞弁制御装置。In an engine exhaust throttle valve control device that includes an exhaust throttle valve in the exhaust passage of the engine and controls the throttle valve to an intermediate opening degree in a predetermined operating state, pressure is applied from a pressure source to a pressure actuator that operates the exhaust throttle valve. A pressure regulating valve is provided in the passage, and the pressure regulating value by the pressure regulating valve is controlled in a direction in which the opening degree of the exhaust throttle valve increases when the negative pressure increases due to the intake negative pressure of the engine. Exhaust throttle valve control device for vehicle engines.
