  • Patent number: 5979598
    Abstract: An intake silencer is designed as a broadband silencer for noises causes by intake of combustion air into internal combustion engines. To achieve the broadband effect, an axial sequence of resonator chambers with different volumes is formed by partitions which extend transversely to the intake pipe in a resonator that surrounds the intake pipe Each resonator chamber communicates through openings in the wall of the intake pipe with the air sucked through the intake pipe. By matching the open surface area of the openings, the thickness of the wall of the intake pipe in the area of the openings and the volume of the resonator chambers, a continuous broadband silencing may be set even over a wide frequency range, the range of practical interest in the present application extending combustion from to 1 to 10 kHz.
