A high compression engine is one that operates with a compression ratio greater than 10:1, often ranging between 10:1 and 14:1 or even higher. These engines compress the air-fuel mixture more than low compression engines, which leads to more power and greater efficiency under ideal conditions. High compression ratios are often found in performance-oriented or […]
