ジンの吸気制御装置。 An intake shutter valve is provided in the intake passage, and the intake shutter valve is fully closed when the engine is stopped, maintained at a constant throttle opening during no-load operation of the engine, and when the accelerator operation amount is a predetermined amount or more. An air intake control device for a diesel engine that opens a valve as the amount of accelerator operation increases during engine load operation, which rotates integrally with the intake shutter valve and constantly controls the intake air by an elastic member. A first lever biased in a direction to open the shutter valve, and a stopper that restricts rotation of the first lever in the valve opening direction, and the stopper is activated in response to an increase in the amount of accelerator operation. a second lever that is rotatably operated to move the rotation restriction position of the first lever toward the opening direction of the intake shutter valve; and a second lever that can be engaged with the first lever; an actuator that rotates the intake shutter valve to a fully closed position by operating the first lever during a stopping operation of the diesel engine.
