Abstract

PURPOSE:To remove fine particles of carbon by combusting the same, by providing an exhaust-gas heating means between a fine carbon particle capturing means, an oxidative catalyst means disposed adjacently of the exhaust-gas heating means and a fuel injection means disposed at an upstream portion of an exhaust-gas passage. CONSTITUTION:Exhaust gas discharged from an engine is introduced from an inlet pipe 6 into a casing 5 and passed, together with fuel supplied from a fuel injection means 8, through pipes 15-17 made of punching metal of stainless steel which are supported by a partition wall 13 and a support plate 19. Carbon contained in the exhaust gas is combusted at a temperaure (about 300 deg.C) sufficiently lower than the temperature (about 600 deg.C) causing spontaneous combustion of carbon of carbon, by the function of an oxidative catalyst 20 charged in the space formed between pipes 15 and 16 which is made of platinum carrying pellets. Heat thus produced is used for combusting and removing fine particles of carbon captured by stainless wool 21 charged in the space formed between pipes 16 and 17. When the temperature becomes lower than a predetermined level, it is detected by a thermocouple 22, and oil ejected from a burner 10 is ignited.
