| Title of Invention | “ A METHOD OF CONTROLLING A MECHANICAL COMPRESSION RATIO BY A VARIABLE COMPRESSION MECHANISM” |
|---|---|
| Abstract | An internal combustion engine provided with a variable compression ratio mechanism (A) able to change a mechanical compression ratio (A) and an actual compression action start timing changing mechanism (B) able to change a start timing of an actual compression action. An amount of intake air in accordance with the required load is fed into a combustion chamber (5) by controlling the closing timing of the intake valve (7), while a pressure in the combustion chamber (5) at the end of a compression stroke is maintained substantially constant regardless of the engine load by controlling the mechanical compression ratio. |
