Does Increasing Compression Ratio Increase Power?

by

Does Increasing Compression Ratio Increase Power? Even with engines having fixed valve timing (non-VVT), the effective compression ratio changes as the engine speed and load change. In short, if it changes the amount of charge in the combustion chamber from cycle to cycle, it changes the expansion ratio, and therefore its power. Does increasing compression
