  "textContent": "Carbon-containing suspended particulates in exhaust gas from an internal combustion engine (10) are collected by a heat-resistant filter (100), and are burned on the filter. It is determined whether there is a need to increase the temperature of the heat-resistant filter (100). If it is necessary to increase the filter temperature, the dynamic pressure on the filter (100) is increased. The conceivable cases where a filter temperature increase is needed includes a case where the exhaust gas temperature is low, a case where the filter (100) is clogged to some extent, etc. If the dynamic pressure on the heat-resistant filter (100) is increased, the filter temperature rises. Therefore, particulates can be effectively removed from exhaust gas while the clogging of the heat-resistant filter (100) is avoided.",
