<p>The present invention relates to an internal combustion engine (1), which is used in motor vehicles, and whose cylinder volume and accordingly the compression ratio (CR) may be changed by the up an down movement of the cylinder sleeve (2) within the engine block (E) in vertical axis. As the sleeve (2) approaches the cylinder head (H), the compression ratio (CR) increases, and as the sleeve (2) 10 descends downwards, the compression ratio (CR) decreases.</p> |
