  • Exhaust gas purifying apparatus for internal combustion engine
    Patent number: 7758833
    Abstract: An exhaust gas purifying apparatus for an internal combustion engine is provided with a NOx removing device and a particulate filter in an exhaust system. A temperature of the exhaust system is detected. A switching control is performed for alternately performing a process for removing sulfur oxide accumulated in said NOx removing device and a regeneration process for burning particulates trapped in said particulate filter, when it is determined to be necessary to perform at least one of the removal of the sulfur oxide in said NOx removing device and the regeneration of the particulate filter. The switching control is performed according to the detected exhaust system temperature.
