Abstract:
An exhaust system includes N heating elements and a particulate matter (PM) filter. The N heating elements heat N portions of an exhaust gas. At least one of the N heating elements is coated with a first selective catalytic reduction (SCR) catalyst. The PM filter has an inlet that receives the N portions of the exhaust gas heated by the N heating elements. Each of the N portions of the exhaust gas heats a corresponding region of the inlet. N is an integer greater than 1.
