-
Compression Ratio Fundamentals
The compression ratio is the ratio of the cylinder volume when the piston is at bottom dead center (BDC) to the volume when the piston is at top dead center (TDC). Reducing the combustion chamber volume through milling effectively increases this ratio. For example, if the initial volume at BDC is 10 units and at TDC is 1 unit, the compression ratio is 10:1. If milling reduces the TDC volume to 0.9 units, the ratio increases to approximately 11.1:1. This seemingly small change can have a significant impact on engine performance.
-
Power and Efficiency Gains
A higher compression ratio generally leads to increased power output and improved fuel efficiency. Compressing the air-fuel mixture more tightly before ignition results in a more powerful and efficient combustion process. This translates to more energy extracted from each combustion cycle, resulting in greater power output and potentially improved fuel economy. However, this relationship is not linear and other factors, like fuel octane rating, play a significant role.
-
Fuel Requirements and Detonation
Higher compression ratios necessitate higher octane fuels. Increased compression generates more heat and pressure within the combustion chamber, increasing the likelihood of detonation, an uncontrolled and potentially damaging form of combustion. Higher octane fuels are more resistant to detonation, allowing for higher compression ratios without incurring engine damage. Choosing the appropriate fuel for the modified compression ratio is critical for safe and reliable engine operation.
