How can the compression ratio be tweaked, and what factors impact coverage and pattern count?

Question

Accepted Answer

Compression ratio can be tweaked by adjusting the volume of the combustion chamber. This affects fuel efficiency and power output.

Compression ratio is the ratio of the volume of the combustion chamber at its largest to its smallest.
Increasing compression ratio can improve fuel efficiency and power output, but too high a ratio can cause engine knocking.
Factors that impact compression ratio include the size and shape of the combustion chamber, the size of the piston, and the stroke length.
Increasing compression ratio can also impact the pattern count and coverage of the engine's combustion.
Optimizing compression ratio requires balancing fuel efficiency, power output, and engine knocking risk.
