Abstract (en)
[origin: EP2617956A1] The device (2) has an exhaust line (5) including a double-flow design in a rear section (X). The double-flow section includes two exhaust pipes (11) with acoustic actuators (12), which are connected to the exhaust pipes in a sound-transmitting manner. The exhaust pipes are unsimilarly designed. The actuators are individually controlled. A time lag device i.e. capacitor (28), is provided in a connection path (27) between one of the actuators and a control device (25). The exhaust pipes have a coupling point (18), at which sound transmission of the actuators to the exhaust pipes takes place. Independent claims are also included for the following: (1) a method for controlling actuators of an exhaust device (2) a motor car.
