The present invention relates to a metering module () 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 () of an internal combustion engine (). The metering module () comprises a metering valve () having a conduit (), a compressed air duct () and a mixing chamber (). An outlet opening of the conduit () for the reducing agent is arranged in the mixing chamber () at a distance from the mid-axis of the metering module ().

Metering module for a liquid reducing agent

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.
