PROBLEM TO BE SOLVED: To quickly complete regeneration of a filter.SOLUTION: Fuel cut is executed by decelerating an internal combustion engine during generation of a filter; when the temperature of a catalyst provided upstream the filter is equal or more than a threshold, post injection is executed; and when the temperature of the catalyst is less than the threshold, while the post injection is restricted, the opening of a throttle is made smaller and the opening of an EGR valve is made larger than those in a state in which the temperature of the catalyst is equal to or more than the threshold. |
