Abstract: Disclosed is a dosing system for a turbocharger turbine of an exhaust system for an internal combustion engine, the dosing system comprising a distribution device and a metering device. The distribution device comprises a receiving surface, and at least one distribution surface. The receiving surface is equipped to receive exhaust additive dosed to the distribution device. The distribution surface is in fluid communication with the receiving surface and is equipped to distribute exhaust additive in an exhaust stream passing through the turbocharger turbine by a rotary motion of the distribution device. The distribution device is attached to a shaft or hub of the turbocharger turbine. The metering device comprises a supply channel, a metering valve, and a dosing pipe arranged downstream of the metering valve in the direction of flow of reductant when dosing. The metering device is arranged to supply exhaust additive to the receiving surface of the distribution device.
