防止装置。In a supercharged internal combustion engine equipped with a resonant supercharging type intake passage, a Helmholtz resonator is connected to the intake passage upstream of the intake compressor of the supercharger, and the intake passage downstream of this connection is used as the resonant supercharging passage. In addition, the resonant frequency of the Helmholtz resonator is made substantially equal to the resonant frequency of the resonant supercharging passage. An intake noise prevention device for an internal combustion engine with a supercharger.
