Abstract

Bu buluş motorlu araçlarda kullanılan ve silindir gömleğinin (2) motor bloğu (E) içerisinde düşey eksende, yukarı aşağı hareket etmesiyle silindir hacmi ve buna bağlı olarak sıkıştırma oranı (CR) değiştirilebilen bir içten yanmalı motor (1) ile ilgilidir. Gömlek (2) silindir kapağına (H) yaklaştıkça sıkıştırma oranı (CR) artmakta ve gömleğin (2) aşağıya doğru inmesiyle sıkıştırma oranı (CR) azalmaktadır.The present invention relates to an internal combustion engine (1) used in motor vehicles, wherein the cylinder liner (2) moves up and down in the vertical axis in the engine block (E) and the cylinder volume and the compression ratio (CR) thereof can be varied. As the liner (2) approaches the cylinder head (H), the compression ratio (CR) increases and the compression ratio (CR) decreases as the liner (2) descends.
