Technical Examples

In an exhaust gas purifying system (b 1) that purifies NOx for the exhaust gas from an internal combustion engine (E) through sulfur purging control by a NOx occlusion reduction type catalyst (41), sulfur purging is judged to have started when the oxygen concentration (Co) detected by an oxygen concentration detector (54) disposed downstream of the NOx occlusion reduction type catalyst (41) drops from a first predetermined oxygen concentration indicating that the NOx discharge condition to a second predetermined oxygen concentration indicating that NOx discharge has ended and that Sox discharge has started. Accordingly, during sulfur purging control by the NOx occlusion reduction type catalyst (41), consideration is given to the discharge of NOx without sulfur purging at the start of sulfur purging control; furthermore, this timing is judged by monitoring the concentration of oxygen downstream of the NOx occlusion reduction type catalyst (41), thus optimizing sulfur purging control.
