Abstract
A fuel-fired burner in a vehicle exhaust system is used to heat up a frozen NOx reducing agent supply tank within a predetermined target amount of time. A method and apparatus are used to identify when a supply of agent is below a predetermined temperature, and the fuel-fired burner is activated for a sufficient amount of time to raise a temperature of the agent to at least the predetermined temperature with the predetermined target amount of time.
