A lance injector assembly for an exhaust component is provided. The lance injector assembly includes a lance and a poppet valve. The lance includes a lance housing, a supply passage fluidly coupled to a reductant source and terminating at a nozzle orifice, and a return passage fluidly coupled to the reductant source. The poppet valve is positioned downstream of the nozzle orifice and includes a poppet movable between a closed position and an open position. When operating in a recirculation mode, the poppet is in the closed position to permit a full portion of reductant supplied to the lance from the reductant source to return to the reductant source. When operating in an injection mode, the poppet is in the open position to permit a first portion of reductant to flow from the nozzle orifice and a second portion of reductant to return to the reductant source.
