摘要： A reductant heating system may include a reductant tank, a reductant tank flange and a hollow tube residing within the reductant tank and passing through the reductant tank flange in two locations to carry coolant into and out of the reductant tank. The reductant heating system may further include a resistive wire wrapped around the hollow tube within the reductant tank and an electrical supply cord located outside of the reductant tank that supplies electrical power to the resistive wire. A temperature detector may be disposed within the reductant tank to detect a temperature within the reductant tank and govern electricity flow to the resistive wire. That is, the temperature detector may be wired in-line in the resistive wire and may be a thermal switch attached to the hollow tube. In another embodiment, the temperature detector may be a thermocouple that senses a temperature within the reductant tank.
摘要翻译： 还原剂加热系统可以包括还原剂罐，还原剂槽法兰和位于还原剂罐内的中空管，并且在两个位置中通过还原剂罐凸缘，以将冷却剂携带到还原剂箱中和从中除去。 还原剂加热系统还可以包括缠绕在还原剂槽内的中空管的电阻丝和位于还原剂箱外部的电源线，该电源线向电阻丝提供电力。 温度检测器可以设置在还原罐内以检测还原罐内的温度并控制电流到电阻丝的电流。 也就是说，温度检测器可以在电阻丝中成直线布线，并且可以是附接到中空管的热开关。 在另一个实施例中，温度检测器可以是感测还原罐内的温度的热电偶。

摘要： 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.
