Abstract: PURPOSE: An exhaust gas post-treatment system and a control method thereof are provided to reduce fuel consumption by recognizing injection of high-sulfur fuel if abnormal desulfurization control is repeatedly implemented. CONSTITUTION: An exhaust gas post-treatment method is as follows. If temperature difference between front and rear ends of a catalyst is below reference temperature difference while reducing agent is jetting, temperature of the catalyst increases to set temperature and the catalyst is desulfurized and regenerated(S310,S320). System decides whether the driving mileage, fuel consumption, and driving time after regenerating is exceeded a first reference value(S330) The supplement state of the fuel is determined according to amount of the fuel supplemented (S340). If the first reference value does not exceed a set reference value, the fuel is supplemented and the temperature difference is below the reference temperature difference while the reducing agent is jetting, the system determines that the high-sulfur fuel is injected(S390).
