Abstract
In accordance with at least one embodiment of an exhaust treatment system whereby parallel sections of exhaust filters such as Diesel particulate filters (DPF's) and a catalyst such as a selective catalytic reduction (SCR) system are integrated together while efficiently maintaining the temperature requirements of both. The parallel exhaust filter sections that may be heated and/or regenerated individually thereby facilitating catalyst temperature control and modulation of pressure drop across the exhaust filters.
