ABSTRACT:
According to one aspect of the present invention, a liquid reductant tank for supplying liquid reductant to a selective catalytic reduction system is disclosed. The tank includes a tank cavity for holding a liquid reductant and being at least partially defined by one or more side walls; a liquid reductant supply line at least partially situated within the tank cavity and for communicating liquid reductant from the tank cavity to outside of the tank cavity; and a heating element situated at least partially within the liquid reductant supply line and for thawing frozen reductant situated within the supply line during cold start conditions to obtain liquid reductant for use in a selective catalytic reduction system.
