Abstract
In an internal combustion engine, a variable compression ratio mechanism which can change the mechanical compression ratio and a variable valve timing mechanism which can control a closing timing of an intake valve are provided. When the variable compression ratio mechanism breaks down, the mechanical compression ratio and the intake valve closing timing are made to change from a current operating point toward a low mechanical compression ratio side demanded operating point without entering the no-entry region.
