EXHAUST EMISSION CONTROL SYSTEM AND METHOD FOR INTERNAL COMBUSTION ENGINES

An NOx storage-and-reduction type catalyst is used which exhibits a saturated NOx storage amount of 5 g or more as NO2 with respect to 1 liter of a catalyst volume at 500 DEG C, and rich spiking is controlled so that an actual NOx storage amount of the NOx storage-and-reduction type catalyst becomes...
