摘要:
Control methods for regenerating particulate filter and an apparatus that includes an internal combustion engine, an exhaust gas conduit in fluid communication with and configured to receive exhaust gas from the internal combustion engine, and a particulate filter assembly in fluid communication with the exhaust gas conduit and configured to receive exhaust gas flowing therethrough. The particulate filter assembly includes a particulate filter to remove particulates from the exhaust gas, a heater device disposed near a front face of the particulate filter, to supply heat for regeneration of the particulate filter after shut-off of the internal combustion engine, and an air pump to input air into the particulate filter to transfer the supplied heat from the heater device to the particulate filter.
