摘要：
A control device for a variable compression ratio internal combustion engine is equipped with a variable compression ratio device capable of changing an engine compression ratio of the internal combustion engine. The control device detects or estimates the temperature of an exhaust component (B11), and sets a target exhaust gas temperature based on the temperature of the exhaust component (B12). A mixing ratio and compression ratio set section (B13) sets a fuel mixing ratio and the engine compression ratio within such a range as not to exceed the target exhaust gas temperature such that energy loss becomes minimum.
