WebCompression ignition (CI) engines are more efficient in comparison to spark ignition (SI) engines due to their high compression ratio; hence, the IC engine is a preferred choice. However, in the CI engines, it is difficult to achieve a homogeneous air–fuel mixture in the combustion chamber prior to the start of the combustion (SOC) process. The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the … See more A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion … See more • Mean effective pressure See more Most engines use a fixed compression ratio, however a variable compression ratio engine is able to adjust the compression ratio while the engine is in operation. The first production … See more The static compression ratio discussed above — calculated solely based on the cylinder and combustion chamber volumes — does not take into account any gasses entering or exiting the cylinder during the compression phase. In most automotive engines, the intake … See more
