When the NO x storage catalyst (14) can store NO x , the temperature of the NO x adsorption catalyst (12) is made to forcibly rise to a target temperature at which the amount of NO x which the NO x storage catalyst (14) can store is desorbed, and the NO x desorbed from the NO X adsorption catalyst (12) is stored in the NO x storage catalyst (14).",
