Abstract: An internal combustion engine of the present invention is an internal combustion engine equipped with a supercharger that can switch between a lean combustion operation that combusts a mixture gas with an air-fuel ratio leaner than a theoretical air-fuel ratio, and a stoichiometric combustion operation that combusts a mixture gas with an air-fuel ratio close to the theoretical air-fuel ratio. Further, the internal combustion engine has an ISC passage that connects an upstream side and a downstream side of a throttle valve in an intake passage, and an ISC valve that regulates an amount of air flowing in the ISC passage. A control device of the present invention performs valve opening control that makes an opening degree of the ISC valve an opening degree larger than a reference opening degree when request torque required by the internal combustion engine is smaller than estimated torque that can be generated in the internal combustion engine, and prohibits switching to the lean combustion operation during execution of the valve opening control.
