摘要:
A device for introducing a liquid reducing agent into the exhaust gas of an internal combustion engine includes an injection device and a retaining device. By means of the latter, the injection device is retained at least indirectly in the vicinity of an exhaust gas conduit and a cooling device cools the retaining device. An intermediate portion is disposed between the retaining device and the injection device, and this portion at least regionally influences the heat flow between the injection device and the retaining device.
