Abstract
An air suction device is provided with an air suction system having at least one capacity-enlarged portion, a compression pump compressing air in synchronization with operation of an engine, a compression air control unit, and a vibration plate which is vibration-excited by air compressed by the compression pump and disposed in a connection passage connecting a discharge side of the compression pump with the capacity-enlarged portion. The compression air control unit controls the phase and amplitude of a pressure variation of compression air discharged from the compression pump, to provide compression air with the pressure variation having the phase opposite to a pressure variation of suction air sucked into the engine.
