の吸気騒音防止装置。In an internal combustion engine having a resonant supercharging type intake passage, a Helmholtz resonator whose resonant frequency increases as the engine speed increases is connected in the middle of the engine intake passage, and the intake passage downstream from this connection is resonantly supercharged. The resonant supercharging channel is characterized in that the resonance frequency of the resonant supercharging increases in synchronization with the resonance frequency g of the Helmholtz resonator as the engine rotation speed increases. Intake noise prevention device for internal combustion engines.
