摘要：
An exhaust system may include a canister that is disposed downstream from an engine. A particulate filter (PF) is disposed within the canister and filters particulates within an exhaust from the engine. A reducing catalyst is disposed within the canister, is on the PF, and promotes reaction of a liquid reductant in the exhaust after reception by the PF. A heating element is disposed within the canister and heats particulate matter in the PF.
