Abstract:
Various systems and methods are described for an engine system with an exhaust gas treatment system including a particulate filter. In one example method, accumulated hydrocarbons are removed from the exhaust gas treatment system by increasing an exhaust gas temperature to a first temperature responsive to a particulate filter regeneration request during extended cold idle operation. After a predetermined duration, the exhaust gas temperature is increased to a second, higher temperature to regenerate the particulate filter.
