Abstract

An internal combustion engine which is provided with a variable compression ratio mechanism able to change a mechanical compression ratio and a variable valve timing mechanism able to control a closing timing of an intake valve. The expansion ratio is made higher at the time of engine low load operation compared with at the time of engine high load operation. A fuel containing alcohol is used as the fuel, and the expansion ratio at the time of engine low load operation is made to fall when an alcohol concentration in the fuel is high compared with when the alcohol concentration in the fuel is low.
