Abstract: An exhaust gas control method of an engine is provided to improve fuel efficiency and torque in accelerating by regulating combustion efficiency and reducing nitrogen oxide, and to increase performance of the engine by minimizing exhaust fluctuation of each cylinder. A nitrogen oxide discharge amount is monitored according to predetermined opening degree of a swirl control valve by receiving data corresponding to engine rpm and a fuel amount, and an excess air ratio is detected and compared with the predetermined value. The nitrogen oxide discharge amount is regulated into the desired value of nitrogen oxide by regulating the opening degree of the swirl control valve in case of the detected excess air ratio to be within the range of predetermined values. The swirl control valve is open-loop controlled in case of the detected excess air ratio to be over the predetermined value, and the nitrogen oxide discharge amount is regulated to the desired value by recirculating exhaust gas.
