<p>PURPOSE:To remove air polluting harmful material in exhaust gas to purify the exhaust gas by additionally providing the exhaust pipe of an engine with a secondary combustion chamber device, and reburning unburnt harmful material in the exhust gas and further secondary reburning it again making use of remaining heat by exhaust gas. CONSTITUTION:Supply ports 2, 2' of air heated to 100 deg.C or higher, that is, hot oxygen, and an intake induction port 4 of sleeve like swage block shape are disposed in a secondary combustion chamber for purifying air pulluting harmful material discharged from the exhaust pipe of an engine in an automobile or the like. A re-combustion chamber 5 covered with fire resisting material 7 excellent in heat accumulation and heat conduction, and a secondary re- combustion chamber 6 of sleeve like swage block shape are also disposed, and cold air supply ports 3, 3' and the like are further disposed. The exhaust gas is then purified being passed through the re-combustion chamber 5 and the secondary re-combustion chamber 6 in this order from the inlet induction port 4 as shown by arrow marks 1-1'''.</p> |
