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 1):
An exhaust purification system for an internal combustion engine comprising:\n an SO X  storing and releasing catalyst able to store and release SO X  in exhaust discharged from the internal combustion engine; a particulate filter arranged downstream of the SO X  storing and releasing catalyst in the direction of flow of exhaust and supporting an oxidation catalyst for trapping soot produced when fuel is burned and ash produced when engine oil is burned; and a control unit configured to be able to perform filter regeneration processing for burning off soot trapped at the particulate filter and SO X  release processing for releasing SO X  stored at the SO X  storing and releasing catalyst, the SO X  released by the SO X  release processing being supplied to the particulate filter, in which exhaust purification system for an internal combustion engine, the control unit is configured: to calculate a time integral showing a sum of the products of a temperature of the particulate filter and the time during which it is maintained at that temperature or a number of times filter regeneration processing is performed; and so that the larger the time integral in the period from when the previous SO X  release processing is performed to when the current SO X  release processing is performed or the greater the number of times the filter regeneration processing is performed, the more increase the concentration of SO X  released from the SO X  storing and releasing catalyst when the current SO X  release processing is performed.
