Fine grain arresting device for internal-combustion engine

Abstract

Abstract PURPOSE:To improve the burning loss efficiency and reduce the pressure loss of a filter member by disposing a pre-filter member made of porous ceramics at the end surface on the exhaust gas inlet side of the filter member, and also disposing an electric heater on the inner side of the pre-filter member. CONSTITUTION:By in candescing the electric heater 5, the fine grain is heated and burnt. Burning is started from the electric heater inserting part and extended to the exhaust gas upstream side. Simultaneously, the calory generated along the stream of the exhaust gas is transmitted to the exhaust gas downstream side. The electric heater 5 is disposed at a position where the density of fine grain in the vicinity of the end surface of the upstream side becomes maximum, that is, at the inner side of the pre-filter 10. By doing so, ignityion becomes easy, and combustion is extended efficiently across the entire region of the filter member 4.
