摘要： To provide a method for controlling a NOx reduction system which can remove NOx with a satisfactorily high efficiency even under low-temperature operating conditions as in diesel cars. The NOx reduction system comprises NOx treatment means disposed in an exhaust passage in an internal combustion engine, and air-fuel ratio control means for bringing the air-fuel ratio of an exhaust gas to a lean or rich state. The NOx treatment means comprises at least a first catalyst layer containing a solid acid catalyst capable of adsorbing ammonia and a second catalyst layer containing a noble metal and a cerium oxide material. The second catalyst layer and the first catalyst layer are stacked in that order on a carrier, and the first catalyst layer constitutes the uppermost layer. The air-fuel ratio control means controls so that the lean state and the rich state are repeated at predetermined intervals. According to the above constitution, NOx is passed through the first catalyst layer in the lean state and is temporarily stored in the second catalyst layer. Thereafter, in the rich state, NOx is converted to NH3 and is restored in the first catalyst layer. When the state is again returned to the lean state, NH3 is converted to nitrogen which is finally released from the first catalyst layer.
