摘要：
This internal combustion engine provided with a variable compression ratio mechanism is equipped with a turbocharger, the opening degree of a wastegate valve is controlled to a target opening degree for each engine operating state, and when the mechanical compression ratio is changed, the target opening degree of the wastegate valve for the current engine operating state is revised.
