CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
In a case where EGR is started in a supercharging region, an opening degree of a waste gate valve (17) is changed at a timing T1 at which an EGR ratio in a first predetermined position changes by valve open of an EGR control valve (21). In a case where EGR is started in a non-supercharging region, a...

| description | In a case where EGR is started in a supercharging region, an opening degree of a waste gate valve (17) is changed at a timing T1 at which an EGR ratio in a first predetermined position changes by valve open of an EGR control valve (21). In a case where EGR is started in a non-supercharging region, a throttle valve (5) is changed at a timing T2 at which an EGR ratio in a second predetermined position changes by valve open of the EGR control valve (21). With these controls, it is possible to suppress an occurrence of torque step upon start of the EGR without distinction between the supercharging region and the non-supercharging region. |
