<p>PROBLEM TO BE SOLVED: To provide a DPF (Diesel Particulate Filter) which prevents generation of any local high temperature in the DPF and erosion and burn-out of the DPF by diffusing the heat generated in a part on which PM of the DPF is easily deposited, and the temperature easily rises, and promotes the combustion of PM by unifying the temperature of the DPF. SOLUTION: In an exhaust emission control device having a DPF 10A to control the particulate matter in the exhaust gas G of a diesel engine, a heat diffusion member 30A of higher heat transmission characteristic than that of the DPF 10A is disposed in contact with a part C, in which the particulate matter in the exhaust gas G of the DPF 10A is easily trapped and deposited, and the temperature easily rises by the oxidation of the deposited particulate matter.</p> |
