There are predicted the amount of nitrogen oxides (NO.sub.x) to be absorbed by an absorbent 125 incorporated in a catalyst 124 and the temperature of the absorbent, based on the running state information obtained from a car navigation system 141 or traffic information service receiver 142, and the r

There are predicted the amount of nitrogen oxides (NO.sub.x) to be absorbed by an absorbent 125 incorporated in a catalyst 124 and the temperature of the absorbent, based on the running state information obtained from a car navigation system 141 or traffic information service receiver 142, and the regenerative operation schedule is determined based on the prediction. Thus, the regenerative operation is conducted at the timing where NO.sub.x has been duly absorbed by the absorbent and the absorbent temperature is lower than a predetermined temperature, so that the leakage of NO.sub.x into the exterior of a vehicle can be restrained.

[ What is claimed is:] [1.] An exhaust gas purifying system for an internal combustion engine, comprising:means for trapping polluting components of exhaust gas emitted from the internal combustion engine;means for regenerating the trapping means by removing the polluting components trapped in the trapping means;means for predicting a future running condition of a vehicle in which the engine is mounted;means for predicting a property of the exhaust gas based on the predicted future running condition;means for determining a timing at which the trapping means should be regenerated by the removal means in accordance with the predicted exhaust gas property; andmeans for executing regenerating of the trapping means by the removing means at the timing determined by the regeneration timing determining means.
