摘要： PROBLEM TO BE SOLVED: To provide an exhaust purification device that accelerates combustion of a combusting agent and reduces ejection of the combustion agent in an uncombusted state.SOLUTION: A valve control part 33 changes an opening degree of a flow rate control valve 16 and controls a flow rate of exhaust flowing through a bypass path 26. By changing the flow rate of the exhaust flowing through the bypass path 26 using the flow rate control valve 16, the flow rate of the exhaust is changed in an exhaust path 21 having exposed heat generating part 24, and a temperature in the heat generating part 24 is changed. An electric resistance R of the heat generating part 24 or a temperature T in the heat generating part 24 is controlled within a range of a predetermined setting temperature Ta by the change of the opening degree of the flow rate control valve 16. Combustion of combusting agent injected from a combustion agent injection valve 13 is accelerated by contact with a high-temperature heat generating part 24. Accordingly, the temperature of the exhaust and an oxidized catalyst 12 is increased.
