| Abstract: | A new combustible gas regeneration technology for diesel particulate filter (DPF) is studied in this paper,which uses combustible gas to burn and eliminate particulates in particulate trapper.The feasibility of this method is verified by theoretical analysis and experiment according to the physical and chemical properties and oxygen contents in exhaust gas,and a device of liquefied petroleum gas (LPG) regeneration method is developed.The characteristics of combustible gas regeneration,including combustible gas flux,the mass of accumulated particulate,and the regeneration interval are studied on engine test bench. |
