Beschreibung
Zusammenfassung:	A liquid reductant dosing module for a combustion exhaust system (5) is disclosed comprising an enclosed reservoir comprising a top, a bottom, one or more sides, an inlet (25), and an outlet (27). A resistive wire rod heater is disposed in that reservoir, comprising a hollow member extending along a first axis between the bottom of the reservoir and the top of the reservoir. Along that member there is disposed resistive metal wire (39) such that when electric current is applied to the resistive metal wire (39), a greater portion of electric power is distributed as heat proximate to the bottom of the reservoir than is distributed as heat proximate to the top of the reservoir.
