摘要： An internal combustion engine comprises a variable compression ratio mechanism capable of varying the mechanical compression ratio and a variable valve timing mechanism capable of controlling the closing timing of an intake valve. In an engine low-load operation, the mechanical compression ratio is maintained at a maximum mechanical compression ratio. In an engine high-load operation, the mechanical compression ratio is gradually decreased as the engine load increases. In the engine high-load operation, a load at which a predetermined mechanical compression ratio lower than the maximum mechanical compression ratio is obtained is preset, and a throttle valve is closed in the range of loads lower than the preset load.

摘要： A spark ignition type internal combustion engine comprises a variable compression ratio mechanism able to change a mechanical compression ratio, an actual compression action start timing changing mechanism able to change a start timing of an actual compression action, and an exhaust valve. At the time of engine low load operation, the mechanical compression ratio is maximized to obtain a maximum expansion ratio, and the actual compression ratio is set so that no knocking occurs. The maximum expansion ratio is 20 or more. The closing timing of the exhaust valve at the time of engine low load operation is made substantially intake top dead center. Due to this, even if operating the internal combustion engine in a state of a large expansion ratio, the temperature of the exhaust purification catalyst can be maintained at a relatively high temperature.
