摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device of a combustion engine, that includes a particulate filter where regeneration treatment is executed using a combustion heat generated when reducing substances within exhaust gas is combusted by an oxidative catalyst, and can achieve the superior regeneration treatment even if the oxidative catalyst is poisoned by sulfur. SOLUTION: A sulfur component detection device 4 is arranged at the upstream of a particulate filter 2 of an exhaust passage 1 and detects a sulfur component within the exhaust gas passing near the oxidative catalyst. The sulfur component detection device 4 includes a holding part that holds SO x and NO x within the exhaust gas and where a limit of holding amount of NO x decreases as a holding amount of SO x increases. The sulfur component detection device 4 estimates the holding amount of SO x based on the holding amount of NO x held by the holding part, and when the holding amount of SO x is a set value or higher, increases an amount of the reducing substances compared with when the holding amount of SO x is less than the set value. The reducing substances are combusted by the oxidative catalyst in the regeneration treatment of the particulate filter. COPYRIGHT: (C)2011,JPO&INPIT
