Abstract
A reagent injection system for reducing emissions from an engine includes a reagent container. A heating element is positioned in a heat transfer relationship with reagent stored within the container. An interchange tube includes a first end in receipt of a recirculated liquid reagent and a second open end positioned in the container. The interchange tube includes a bleed-off tube branching off of the interchange tube between the first and second ends. A terminal end of the bleed-off tube is positioned within a vapor dome above a surface of the reagent.
