Abstract
(EN)
An exhaust purification device comprises a filter 33 that is provided to an exhaust passage 13 of an internal combustion engine 10 and traps particulate substances in exhaust, an NOx occlusion reduction catalyst 32 that is provided to the exhaust passage 13 and reduces and purifies NOx in the exhaust, and a regeneration control unit 50 that executes a filter regeneration process of raising the exhaust temperature to a prescribed temperature and burning out particulate substances that have accumulated in the filter 33, and a catalyst regeneration process of richening the exhaust and reducing and purifying the NOx occluded in the NOx occlusion reduction catalyst 32. The regeneration control unit 50 starts the filter regeneration process after executing the catalyst regeneration process when the filter regeneration process is to be executed.
