摘要

The system has an exhaust gas treatment device e.g. diesel particle filter, arranged in a exhaust pipe (10), and injection devices (28, 30) arranged in front of the treatment device in a flow direction (12) for introducing a lubricant in to the exhaust pipe. A driving turbulence element (18) is arranged in the exhaust pipe in close-up-range of one of the injection devices. A drive device is provided for driving the turbulence element, which is arranged in front of the device (30) and at back of the device (28) in the flow direction. A control device controls the drive device.
