How to determine engine compression ratio
WebThis simple tool allows you to calculate the STATIC compression ratio of an engine. It will also allow you to calculate the engine displacement in Liters and Cubic Inches. See Below for explanations of the fields required. Engine Data Explanation Calculate your Engine's Compression Ratio Here. WebDynamic compression. Calculating static compression is simply the ratio of the total volume in the cylinder at bottom dead center (BDC) to the compressed volume at top dead center (TDC). The dynamic compression ratio is similar as it is the ratio of volumes. The compressed volume is the same in both static and dynamic compression.
