    摘要： A mixing device for mixing the exhaust gas of an internal combustion engine flowing in an exhaust pipe with a reducing agent as well as an exhaust gas purification system having such a mixing device, in which a mixing body is positionable in the exhaust pipe and which includes a gas impact surface and a spray impact surface so that exhaust gas flowing from the internal combustion engine is able to strike the gas impact surface and reducing agent, which is suppliable transversely to the exhaust gas flow, is able to strike the spray impact surface, the spray impact surface and the gas impact surface forming disjointed sub-areas of the surface of the mixing body. The mixing device distributes the reducing agent uniformly over the cross section of the exhaust pipe and mixes it uniformly with the exhaust gas.

    摘要： The invention relates to a metering system for injecting pollutant reducing medium into an exhaust system includes a metering pump, and at least one self-opening nozzle for injecting fluidic media into the exhaust gas system. The nozzle is self-opening with a needle chamber, a nozzle needle and a spring chamber with a spring element. The needle chamber and spring chamber are separated by a flexible membrane which prevents fluidic media from escaping from the needle chamber into the spring chamber, and also permits an excess pressure to prevail in the needle chamber in relation to the spring chamber, causing the nozzle needle to be displaced in opposition to a spring force, thus releasing a nozzle opening. The inventive metering system is cost-effective, robust and can also be used at low operating temperatures.

    摘要： An exhaust gas purification system for purifying the exhaust gas of an internal combustion engine, especially an internal combustion engine featuring auto-ignition and/or direct fuel injection, is provided. The system includes at least one oxidation catalytic converter disposed in an exhaust gas duct of the internal combustion engine, at least one device for selective catalytic reduction of the exhaust gases which is installed downstream of the oxidation catalytic converter, and a feed device for feeding reducing agent into the exhaust gas stream upstream of, or in, the device for selective catalytic reduction. A switch-over device is provided for selectively feeding reducing agent into the exhaust gas stream upstream of, or inside, the at least one oxidation catalytic converter. A corresponding method for purifying the exhaust gas of an internal combustion engine is also provided.
