An object of the present invention is to increase opportunities that a filter is regenerated. Provided is an exhaust purification apparatus for a spark ignition type internal combustion engine, the apparatus including a catalyst and a filter in an exhaust passage of the internal combustion engine, and a control device that prohibits fuel cut when thermal degradation of the catalyst is predicted to advance in the case of implementing a fuel cut. The control device executes the fuel cut even where thermal degradation of the catalyst is predicted to advance, when regeneration of the filter, which is processing of removing particulate matter trapped in the filter, is needed. |
