Abstract

An occluding member is provided in an exhaust system of an internal combustion system, to thus trap and desorb a plurality of types of hydrocarbons having different boiling points. First calculation means estimates a distribution of presence of the hydrocarbons to be trapped by the occluding member for each type and calculates an occlusion quantity of the occluding member 2 from the quantity of trapped hydrocarbons for each type. Further, there is performed control for purifying the hydrocarbons occluded in the occluding member according to the occlusion quantity calculated by the first calculation means.
