A supercharged internal combustion engine is provided that is capable of introducing EGR gas into an intake passage on an upstream side relative to a compressor. When a required WGV opening degree is less than a lower limit value WGVmin in a case in which introduction of EGR gas is started under a situation in which the temperature of an EGR valve is less than or equal to a predetermined value X1, the WGV opening degree is controlled during a protection time period T3 after introduction of EGR gas starts by using the lower limit value WGVmin as the required WGV opening degree. |
