Abstract

See full text

An internal combustion engine which is provided with a variable compression ratio mechanism which can change a mechanical compression ratio and a variable valve timing mechanism which can control a closing timing of an intake valve. A target operating point which can be reached after a fixed time without entering no-entry regions from the current operating point toward an operating point which satisfies the demanded intake air amount is calculated for an operating point which shows a combination of the mechanical compression ratio and the closing timing of the intake valve when the demanded intake air amount changes, and the mechanical compression ratio and the closing timing of the intake valve are made to change toward this target operating point.
