<p>An exhaust emission control device capable of surely regenerating a DPF without melting down the DPF by burning particulates collected by the DPF always in appropriate state of combustion, wherein an ECU predicts the amount of particulates collected by the DPF (S6), selects a map according to whether the collected amount is appropriate or excessive (S8), obtains a target amount of oxygen from a DPF temperature based on the selected map (S10, S12), and gives the feed back of the amount of oxygen in exhaust emission to the target amount of oxygen (S20), whereby, since the collected amount of the particulates is reflected on the control of the amount of oxygen, the particulates can be burned always in an appropriate state of combustion irrespective of the collected amount of the particles.</p> |
