VARIABLE COMPRESSION RATIO DEVICE AND INTERNAL COMBUSTION ENGINE USING THE SAME |
| 摘要 |
A variable compression ratio device and an internal combustion engine are disclosed. The variable compression ratio device includes a main piston that moves in a reciprocating manner, a main combustion chamber having a volume that is varied by the main piston, a sub-compression chamber communicating with the main combustion chamber; a sub-piston configured to reciprocate in the sub-compression chamber to vary a volume of the sub-compression chamber; and a sub-piston reciprocating unit that reciprocates the sub-piston. Accordingly, the air-fuel ratio and output of the internal combustion engine can be improved. |
