Apparatus For Mixing An Additive With A Gas Flow

An exhaust gas system that comprises an apparatus for mixing an additive with a gas flow, said apparatus comprising

• a mixing chamber which can be flowed through by at least a portion of the gas flow, said mixing chamber having at least one inlet opening through which a main inlet flow of the gas flow flows into the mixing chamber on operation of the apparatus, having at least one metering opening and having at least one outlet opening;
• and
• a metering device by means of which an additive flow of the additive can be introduced into the mixing chamber through the metering opening, wherein the inlet opening and the metering opening are arranged and formed such that the main inlet flow and the additive flow flow in substantially opposite directions into the mixing chamber so that the main inlet flow and the additive flow impact one another.

A vehicle comprising an internal combustion engine that is connected to an exhaust gas system that comprises an apparatus for mixing an additive with a gas flow, said apparatus comprising

• a mixing chamber which can be flowed through by at least a portion of the gas flow, said mixing chamber having at least one inlet opening through which a main inlet flow of the gas flow flows into the mixing chamber on operation of the apparatus, having at least one metering opening and having at least one outlet opening;
