<P>PROBLEM TO BE SOLVED: To carry out filter regeneration processing in an early stage by speedily raising a temperature of a diesel oxidation catalyst. <P>SOLUTION: A burner device 200 which is arranged before a diesel oxidation catalyst 130 oxidizing exhaust gas in an exhaust path 110 of a diesel engine 100 includes: an inflow path 210 in which exhaust gas branching off from the exhaust path flows in; a combustion chamber 212 where mixed gas of the exhaust gas and fuel is burnt and exhaust gas after the burning flows out to the exhaust path; a burner catalyst 214 which is provided in the combustion chamber and accelerates the burning; a combustion fuel supply part 216 which supplies fuel to the burner catalyst; a combustion flow rate control mechanism which limits the rate of inflow from the inflow path to the combustion chamber; and a flame heating part 220 which heats the burner catalyst with flames. <P>COPYRIGHT: (C)2013,JPO&INPIT |
