Why do 2 strokes have low compression ratio?
Why do 2 strokes have low compression ratio? Worn piston rings can cause incomplete sealing, resulting in lower compression and more difficulty in starting. Worn piston rings or reed valves that are no longer sealing properly may be the cause of the poor startability characteristic. What's better higher or lower compression ratio? A higher compression ratio (CR) is beneficial for engines. That's because the higher ratio allows for an engine to extract more energy from the combustion process due to better thermal efficiency. Higher compression ratios allow the same combustion temperatures to be achieved with less fuel. How is the...
