    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 internal combustion engine has an exhaust treatment system for reducing pollutants in the exhaust. The system includes a reservoir containing an active ingredient a delivery device for delivering the active ingredient and an injection device for injecting the active ingredient into the exhaust. According to the present invention, the exhaust treatment system includes a pressure reservoir that is fed by the delivery device; this pressure reservoir is able to store the active ingredient under pressure and is directly connected to the injection device.
