Abstract (en)
[origin: EP2581567A1] The absorber has a connecting pipe (8) for acoustic and fluidic connection of a housing (7) with an exhaust system (1). An active membrane (10) separates front volume (12) from rear volume (13) in the housing, and is connected with the connecting pipe. An actuator stimulates vibration of the active membrane, and a condensation line (14) i.e. pipe, fluidically connects the rear volume with the front volume, in which vapor contained in the exhaust gas is condensed, where the condensated vapor is directed to the front volume.
