Patent ID: 7168241

Claim:
A device for introducing fuel into an exhaust line of an internal combustion engine, the device comprising a fuel injector for injecting fuel under an injection pressure into the exhaust line through a radial opening in a pipe section of the exhaust line, wherein the fuel injector is connected to a coolant circulation system in a manner suitable for heat transfer, wherein the fuel injector is mounted on an injector mount, said injector mount beings mounted in turn on the pipe section, the injector mount is connected to the coolant circulation system in a manner suitable to transfer heat, so the fuel injector is connected not directly, but indirectly through or via the injector mount to the coolant system in a manner suitable for heat transfer, the injector mount comprises an injector receptacle which passes radially through the injector mount and opens into the radial opening of the pipe section, the fuel injector is inserted into the injector receptacle so that an injector head of the fuel injector is in the area of the radial opening, the coolant circulation system is connected to a coolant circulation of the internal combustion engine, the fuel injector is connected to a fuel supply system of the internal combustion engine, and the fuel injector is supplied with fuel from a fuel reservoir from which also the internal combustion engine is supplied with fuel.
