Embodiment Construction
[0031] figure 1 A motor vehicle 14 with an internal combustion engine 15 and an exhaust gas system 16 is shown. The internal combustion engine 15 is preferably a diesel engine or a lean-burn (with excess air) gasoline engine. In this example, the exhaust gas flow 3 in the exhaust system 16 first flows (overflows) through the first exhaust gas purification element 20 and, after flowing through the mixing section 5 , through the second exhaust gas purification element 21 . In this example, an oil injector 19 is connected directly to the connection to the first exhaust gas purification element 20 , which injects the additive 2 into the exhaust gas flow 3 . Arranged in the adjacent mixing device 1 are plates 10 which are oriented in the main flow direction 8 of the exhaust gas flow 3 . This device is a preferred device established in the prior art, but said device does not constitute a restriction of the concept of the invention. The exhaust gas line 6 in the region of the mixi...
