Abstract
Methods and systems are provided for regenerating a particulate filter of a vehicle. In one example, a method may include, during a non-engine operating condition, regenerating a particulate filter coupled in an exhaust system downstream of an engine by activating an electric heater of the particulate filter and directing intake air through the particulate filter, the intake air bypassing the engine, and adjusting an electrical load of the electric heater responsive to one or more of exhaust temperature and intake airflow.
