    Abstract: A system for purifying an exhaust gas and an exhaust system having the same while preventing degradation of a selective reduction catalyst may include an exhaust pipe connected to an engine, the exhaust gas generated at the engine passing through the exhaust pipe, a particulate filter mounted on the exhaust pipe, coated with a selective reduction catalyst adapted to reduce nitrogen oxides contained in the exhaust gas by an injection of a reducing agent, and adapted to trap particulate matters contained in the exhaust gas, and one or more injectors adapted to inject the reducing agent and/or oxygen storage capacity material together or separately into the exhaust gas passing through the exhaust pipe.

    Abstract: An exhaust purification system for an internal combustion engine, and a desulfurization method for the same, recovers purification performance of a denitrification catalyst by removing sulfur poisoned at the denitrification catalyst in an exhaust system. The exhaust purification system may include an exhaust pipe through which an exhaust gas flows, the exhaust gas being generated at the internal combustion engine having a first injector injecting a fuel to a combustion chamber, a second injector mounted at the exhaust pipe and additionally injecting the fuel, a particulate filter mounted at the exhaust pipe downstream of the second injector and filtering particulate matters (PM) in the exhaust gas, a denitrification catalyst mounted at the exhaust pipe downstream of the particulate filter and reducing nitrogen oxide contained in the exhaust gas, and a control portion performing desulfurization of the denitrification catalyst when a desulfurization entering condition and a desulfurization condition are satisfied during regenerating the particulate filter.
