Abstract

Abstract: An acoustic attenuator (10) for damping pressure vibrations in an exhaust system of an engine, the acoustic attenuator comprising a body (16) which is provided with a gas inlet (18) and a gas outlet (20) at opposite ends thereof, and a gas passage duct (24) arranged between the inlet and the outlet inside the body, where in the body encloses a first resonator chamber and a second resonator
chamber. The body is provided with a common inlet (34) communicating with the first and the second resonator chambers (36, 38), and the resonator chambers (36, 38) are arranged to extend from the common inlet (34) towards the opposite ends (25) of the body (16).
