Patent ID: 8596063

Claim:
A reductant delivery system for an exhaust treatment system of an internal combustion engine comprising: a turbocharger fluidly coupled to, and configured to receive exhaust gas from, the internal combustion engine; an exhaust gas driven turbine wheel disposed for rotation in a turbine housing of the turbocharger; a reductant injection device coupled to and extending through the turbine housing, the reductant injection device in fluid communication with the turbine wheel of the turbocharger; a reductant storage tank; and a conduit system fluidly connecting the reductant injection device with reductant in the reductant storage tank for delivery of the reductant to the reductant injection device, and from the reductant injection device directly into the turbine housing of the turbocharger upstream from the exhaust gas driven turbine wheel disposed therein.
