Abstract
In an exhaust system, there are provided an HC absorbent which absorbs HC contained in exhaust when in a specified low-temperature range and desorbs the absorbed HC when it exceeds said low-temperature range, and a catalyst capable of at least removing HC by oxidation, where the catalyst is arranged at the same position as or downstream of the HC absorbent. When it is found that the HC absorbent is in a state ready for desorbing the absorbed HC (S, S) and the internal combustion engine is in a specified decelerating state (S), fuel supply to some of the cylinders of an internal combustion engine is stopped while fuel is supplied to the other cylinders (partial fuel cut) (S).
