    摘要: An exhaust gas control apparatus includes a second catalyst converter (35) having an exhaust gas control function in an exhaust passage (14) in an engine (10). In the exhaust gas control apparatus, the second catalyst converter (35) is recovered by burning and removing particulate matter accumulated in the second catalyst converter (35). In the exhaust gas control apparatus, when the engine (10) (vehicle) is decelerated while an amount of the accumulated particulate matter is large during recovery of the catalyst, an increase in an amount of air taken in a combustion chamber (13) is suppressed by a large amount, as compared to when the engine (10) (vehicle) is decelerated while the amount of the accumulated particulate matter is small.
