摘要： PROBLEM TO BE SOLVED: To prevent cracking of a diesel particulate filter (DPF) 13 caused by the combustion of after-injected fuel in an engine constituted to perform after-injection of fuel to burn soot by raising the temperature of the DPF 13. SOLUTION: An oxidation catalyst 12 is disposed in an exhaust passage 11 upstream of the DPF 13. The direct supply of the after-injected fuel to the DPF 13 is thereby prevented, and the temperature of the DPF 13 is raised by the combustion reaction heat of the after-injected fuel at the oxidation catalyst 12 to burn the soot.
