Abstract:
A device for delivering reducing agent from a tank to a metering unit includes a pulsating delivery pump for delivering reducing agent in a delivery direction through a delivery line from the tank to the metering unit. The delivery line includes at least two separate ducts in regions downstream of the delivery pump in the delivery direction. The ducts form flow paths having different propagation times for the reducing agent. This leads, in particular, to cost-effective noise reduction for such delivery systems. A motor vehicle having the device is also provided.
