、内燃機関の吸気音減衰装置。 A resonance box is connected to the intake passage of the internal combustion engine through a communication pipe, and the communication pipe is provided with a control valve that controls its opening area in two stages, large and small. In an intake noise damping device for an internal combustion engine, the actuator is connected to a position where the opening area of the communicating pipe is reduced, and when operating at high speed, the opening area of the communicating pipe is enlarged. The invention is characterized in that the control valve is configured such that when the engine is in a state, the control valve is moved to a position where the area of the communication pipe opening is reduced, and when the engine is stopped, the control valve is set to an inoperative state and the control valve is operated to a position where the area of the communication pipe opening is enlarged. Intake noise damping device for internal combustion engines.
