装置。An intake throttle valve and an exhaust throttle valve are provided in the intake passage and the exhaust passage of the engine, and at least one of the pressure-type actuators that drive the intake throttle valve and the exhaust throttle valve is controlled by the pressure acting on the pressure-type actuator. In an engine equipped with a pressure control valve that corrects according to the opening degree of the throttle valve, and configured to close both valves during a specified engine operation, the dual pressure actuator is connected to a branch pressure passage connected to each actuator and the branch pressure It is connected to a pressure source via a common on-off valve disposed in the pressure passage upstream of the branching part of the passage, and delays the flow of fluid in the upstream direction within the branch pressure passage and upstream of the pressure control valve. An engine intake/exhaust throttle valve control device characterized by being provided with a delay valve.
