A spark-ignited internal combustion engine includes a variable compression ratio mechanism that changes a mechanical compression ratio and an actual compression ratio start timing-changing mechanism that changes a start timing at which actual compression starts. An actual compression ratio is changed according to the specific heat ratio of an intake gas that is supplied into a cylinder.
