Abstract
A regeneration control device for an exhaust purification device includes a regeneration controller that executes regeneration control in which particulate matters trapped by a filter are removed by combustion, and a post-injection controller that during the regeneration control, executes control in which a time period of a post-injection of fuel executed subsequently to a main injection of fuel is advanced such that a supercharging pressure of a turbosupercharger becomes higher than a supercharging pressure during steady operation.
