摘要：
In an internal combustion engine, the engine is formed so that an output of an electric motor can be superposed on an output of the engine. An SOX trap catalyst able to trap the SOX contained in the exhaust gas is arranged inside the engine exhaust passage upstream of the NOX storage catalyst. The vehicle drive power from the engine and the vehicle drive power from the electric motor are adjusted so that the SOX trap rate of the SOX trap catalyst is maintained at a predetermined high SOX trap rate.
