To calculate the ratio for your vehicle, you need to use the formula, compression ration = volume at below dead center divided by volume at top dead center. This is not as simple as it sounds but if you know a few key measurements, you will be able to calculate the compression ratio.What is effective compression ratio?
The effective compression ratio is what the engine sees while running. While the static CR is defined simply by the geometry of the engine, the effictive CR is influenced by multiple factors such as the engine geometry, cam timing, intake pressure, connecting rod length, and volumetric efficiency.How to calculate engine compression ratio and displacement?
Calculating compression ratio Using the engine displacement and the combustion chamber volume the compression ratio can be easily calculated. Simply add the displacement to the combustion chamber volume and then divide the answer by the combustion chamber volume.
