摘要： In order to perform an optimal operation for regeneration an exhaust gas purifying system (124), the amount of nitrogen oxide (C) absorbed by a catalyst (125, 812) and an exhaust gas temperature (T) are predicted based on the running condition information obtained from a car navigation system (141, 841) or the like after the present time. On the basis of these predictions, a regeneration timing is determined as a time when the amount absorbed by the catalyst (125, 812) is large and the exhaust gas temperature (T) is within a predetermined temperature range. When the predicted regeneration timing occurs, the exhaust gas is enriched so that the nitrogen oxide is released from the catalyst (125, 812) thereby to regenerate the catalyst (125, 812). Note, the nitrogen oxide released from the catalyst (125, 812) is reduced to a harmless substance by hydrocarbons, etc. which remain unburned in the exhaust gas. When the present invention is applied to a particulate filter (814) of the diesel engine, the frequency of performing the operation of increasing the exhaust gas temperature (T) is reduced, and it is possible to suppress the deterioration of the fuel consumption rate.
