Patent ID: 8234854

Claim:
A system for heating a reducing agent associated with a reducing agent distribution system, comprising: a reducing agent containment device; a distribution device connected to the reducing agent containment device and configured to dose a quantity of reducing agent to an exhaust conduit; at least one heating component associated with the reducing agent containment device; a temperature sensor configured to determine a temperature of the reducing agent, the temperature sensor disposed at least partially within the reducing agent containment device; a pressure sensor associated with the distribution device, the pressure sensor configured to determine a pressure characteristic of the system; a recirculation line disposed between the distribution device and the reducing agent containment device; and a controller configured to receive input from the temperature sensor and the pressure sensor and configured to send input to the at least one heating component based on the input received from the temperature sensor and the pressure sensor the controller being further configured to measure a first time period and activate the recirculation line based on the first time period exceeding a threshold and before any reducing agent is dosed to the exhaust conduit.
