Which one has higher a compression ratio, SI or CI engine?
Interesting. Do all CI engines have higher compression ratios than SI engines?
It's a general rule of thumb, but there may be exceptions depending on the specific design of the engine. Additionally, it's worth noting that compression ratio is just one factor that affects engine performance, and there are many other design considerations that can impact an engine's efficiency, power output, and overall performance.
