<p>PURPOSE:To reduce the amount of cinders of many particulates which remain on the circumferential part of a filter when the filter is regenerated, in relation to the exhaust purifying deice of a diesel engine. CONSTITUTION:A gas suction pipe 6 is provided in the vicinity of the outer circumferential side of a filter end surface 1b provided opposite to the side on which an end surface heater 2 is provided so as to suck exhaust gas at the time of collection of particulates and gas for regeneration at the time of regeneration of a filter by an electrically driven air pump 9. As a result, flow of gas is promoted along the filter outer circumferential part, and it is possible to reduce the amount of cinders of the particulates at the time of regeneration.</p> |
