Abstract (en)
[origin: US2011072805A1] An exhaust gas aftertreatment system (10) for a vehicle having an engine (14) includes a fluid passageway (20) extending from the engine to an ambient (18) for fluidly communicating exhaust gas (F). A diesel particulate filter (30) is disposed on the fluid passageway downstream of the engine (14). Disposed downstream of the engine (14) and upstream of the diesel particulate filter (30) is an electric diesel oxidation catalyst (24) having a substrate (34). A first electrode (40) and a second electrode (46) are attached to the electric diesel oxidation catalyst (24). The first electrode (40) selectively delivers current through the substrate (34) to the second electrode (46) to generate heat at the substrate (34).
