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 3):
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 control unit is configured so that the larger the time integral or the greater the number of times the filter regeneration processing is performed, the greater the rich degree of the air-fuel ratio of the exhaust when the SO X  is released by the SO X  release processing.
