摘要： An exhaust gas control apparatus for an internal combustion engine includes a NOx purification catalyst disposed in an exhaust passage of the internal combustion engine and carrying a first catalyst metal on a first catalyst carrier, an oxidation catalyst disposed in the downstream exhaust passage of the NOx purification catalyst and carrying second catalyst metals including a base metal on a second catalyst carrier, an air introduction apparatus introducing air into an upstream of the oxidation catalyst, and a temperature detector detecting a temperature of the oxidation catalyst. When an oxidation catalyst temperature is a predetermined temperature or lower, an air- fuel ratio of the exhaust gas into the oxidation catalyst is controlled to a more fuel lean ratio than the stoichiometric air- fuel ratio. When the oxidation catalyst temperature exceeds the predetermined temperature, the air-fuel ratio of the exhaust gas into the oxidation catalyst is controlled to the stoichiometric air-fuel ratio.
