Abstract

PURPOSE:To improve ignition performance of a collected particulate by means of a heating device and to make burning of the particulate not to be blown off by an exhaust gas flow, by providing a heating device which ignites and burns and a valve which is provided within a bypass and opens and closes the bypass. CONSTITUTION:At the time of collection of a particulate by a filter component material 5, a duct 40b is kept closed by a reed valve 8. The particulate in exhaust gas to be discharged through an exhaust gas collecting pipe 2 and an exhaust pipe 3 of an internal-combustion engine 1 is collected according as it passes through the filter component material 5. When a pile of the particulates comes to a predetermined measure, a signal is sent to a valve actuation device 15 from a control circuit 12, the duct 40b is closed by actuating the reed valve 8 and an exhaust gas flow to a duct of a filter side partitioned by a separation plate 7 is reduced. At the same time, an electric heater 6 provided on the filter component mateial 5 is electrified and heated at red heat, through which burning is started by heating the particulates collected around the heater.
