Conventionally, in a region such as a high rotation speed and high load region of an internal combustion engine, increase in amount of fuel or the like is performed in order to prevent excessive temperature rise in such an exhaust component as a catalyst, an exhaust pipe and the like beyond a limit value. In a technology of preventing such an excessive temperature rise in the exhaust component as recited in Patent Literature 1, in a variable compression ratio internal combustion engine equipped with a variable compression ratio device capable of changing an engine compression ratio, a value of increase in amount of fuel is set in accordance with the engine compression ratio. Specifically, as the engine compression ratio becomes higher, thermal efficiency is further enhanced and the temperature of exhaust gas is decreased. Therefore, the value of increase in amount of fuel is set such that as the engine compression ratio becomes higher, the value of increase in amount of fuel becomes smaller.
