Abstract
A catalyst is positioned downstream of a thermal enhancer, such as a fuel-fired burner for example. A doser injects hydrocarbons into the thermal enhancer to maintain exhaust gas temperatures such that the catalyst is in an active condition and to raise exhaust gas temperatures to a level such that a diesel particulate filter can be regenerated.
