    摘要： A NOx storing catalyst (11) comprising a precious metal catalyst (46) and NOx absorbent (47) is arranged in an exhaust passage. When the air-fuel ratio of the exhaust gas is lean, the storing catalyst cold stores the NO2 contained in the exhaust in the absorbent when the catalyst is inactive and hot stores the cold stored NO2 in the absorbent when the catalyst is made active. The NO2 contained in the exhaust is cold stored in the absorbent when the catalyst is not activated, and when a predetermined NOx storing catalyst restoring condition (107) is met, a NOx storing catalyst restoring control (109, 115) including raising the NOx storing catalyst temperature to a predetermined temperature to active it (109) is executed so as to restore the cold storing capability of the NOx absorbent.

    摘要： An exhaust temperature raising apparatus for an internal combustion engine includes an exhaust throttle valve that adjusts an amount of flow of an exhaust gas flowing in an exhaust passage, a valve control device for controlling the exhaust throttle valve to a substantially completely closed state at a time when an amount of an unburned fuel component contained in the exhaust gas is to be reduced, an engine air-fuel ratio control device for operating the internal combustion engine at a theoretical air-fuel ratio or a fuel-excess air-fuel ratio when the exhaust throttle valve is controlled to the substantially completely closed state by the valve control device, and a secondary air supply device for supplying a secondary air to an upstream portion of the exhaust passage when the exhaust throttle valve is controlled to the substantially completely closed state by the valve control device.
