Abstract:
An exhaust purification system for an internal combustion engine provided with an SO X  storing and releasing catalyst and a particulate filter arranged downstream of the SO X  storing and releasing catalyst. SO X  release processing is performed for releasing SO X  stored in the SO X  storing and releasing catalyst. The SO X  released by the SO X  release processing is supplied to the particulate filter. The larger a time integral showing a sum of products of a temperature of the particulate filter and a time during which it is maintained at that temperature from when SO X  release processing was performed, or the greater the number of times the filter regeneration processing is performed, the greater the concentration of SO X  released by the SO X  release processing.

Claim (Index 4):
The exhaust purification system for an internal combustion engine according to  claim 1 , wherein\n the SO X  storing and releasing catalyst is comprised of an SO X  storage and reduction type catalyst able to absorb SO X , the SO X  release processing is processing for making the air-fuel ratio of the exhaust rich to thereby make the SO X  storage and reduction type catalyst release SO X , and the system is provided with an oxygen storing and releasing catalyst for absorbing oxygen when the air-fuel ratio of the exhaust is lean and releasing oxygen when the air-fuel ratio of the exhaust is rich between the SO X  storing and releasing catalyst and the particulate filter.
