  • Metering module for a liquid reducing agent
    Patent number: 8863502
    Abstract: The present invention relates to a metering module (15) for a liquid reducing agent, in particular a urea-water solution, for mixing the reducing agent with a gas, in particular air, for further introduction into an exhaust pipe (5) of an internal combustion engine (1). The metering module (15) comprises a metering valve (31) having a conduit (33), a compressed air duct (49) and a mixing chamber (35). An outlet opening of the conduit (33) for the reducing agent is arranged in the mixing chamber (35) at a distance from the mid-axis of the metering module (36).

  • Device and method for producing a reducing agent air-mixture
    Patent number: 6848251
    Abstract: A device for generating a mixture of reducing agent and air, having a mixing space into which reducing agent via a reducing agent delivery conduit and air via an air delivery conduit can be introduced into the mixing space, having means for pressurizing the air, in such a way that the air flows essentially at the speed of sound through the air delivery conduit.
