  • Patent number: 11015508
    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.

  • Publication number: 20190072029
    Abstract: Provided is a compressor arrangement in an air line supplying charged air to a combustion engine. The compressor arrangement comprises a compressor unit comprising a housing including an air intake passage, a compressor wheel arranged in said air intake passage, and an additional air passage allowing recirculation of air from the air intake passage in a position radially outwardly of a part of the compressor wheel. The additional air passage is configured to allow recirculation of air to an air conduit delivering an air flow to the air intake passage of the compressor unit.
