Broad-band resonance silencer, in particular for a motor vehicle engine

A method of noise damping using a broad-band resonance silencer or an engine or turbocharger of an internal combustion engine having the broad-band resonance silencer, wherein in addition to broad-band damping the at least one or each acoustic passage has a or precisely one passage inlet opening, through which the fluid or gas flows thereinto and is closed at the end to function as a lambda/4 passage or a lambda/2 passage, and

• wherein the broad-band resonance silencer comprises
• an at least two-part housing (2) which defines a silencer longitudinal axis and a silencer transverse axis, an exhaust gas-carrying or gas-carrying pipe (4.1) which is accommodated in the housing and which with a circumferentially surrounding pipe jacket with acoustic openings therein defines a pipe interior, wherein the pipe (4.1) in the installed position is enclosed by at least one damping chamber which is formed by the housing and which is operatively connected to the pipe interior by way of the acoustic openings (4.2), wherein the housing (2) comprises at least two housing portions, in particular two divided housing half-shells (2.1, 2.4), wherein the pipe (4.1) is in the form of a pipe insert body (4) which includes a central pipe portion with two front pipe ends,
• wherein the pipe insert body (4) is adapted to be inserted into the housing portions of the housing (2),
• wherein the damping chamber is subdivided into at least two resonance chambers by way of at least one insert bar (4.3), wherein the broad-band resonator can also be in the form of a Helmholtz resonator,
• wherein the at least one insert bar (4.3) is provided on the insert body (4) in one piece therewith,
• wherein the insert bar (4.3) also functions as a position fixing means for the pipe insert body in relation to the housing,
• wherein in addition to the broad-band resonator at least one acoustic passage (4.5, 4.6, 4.11, 4.12, 4.13, 4.15, 4.20) providing a tubular resonator volume is provided, the passage inlet opening (4.11, 4.12) of the acoustic passage is provided in the pipe insert body, and the acoustic passage
• (i) extends at least portion-wise spaced from the pipe jacket forming an intermediate space between the passage (4.5, 4.6, 4.11, 4.12, 4.13, 4.15, 4.20) and the pipe (4.1), and/or
• (ii) extends in the direction of the silencer longitudinal axis over a plurality of damping chambers.
