WebDCR is derived from measured or calculated values that are the actual dimensions of the engine. Therefore, unless variable cam timing is used, just like the static compression ratio, the Dynamic Compression Ratio, is fixed when the engine is built and never changes during the operation of the engine. Two important points to remember: Web1 apr. 2024 · The following are needed to calculate the compression ratio: the actual cylinder bore and stroke measurements, the head gasket compressed thickness, the piston dome volume, the piston deck-height volume (where the top of the piston is in relation to the head gasket surface at TDC) and the combustion chamber volume.
