"Compression ratios are often between 14:1 and 23:1 for direct injection diesel engines, and between 18:1 and 23:1 for indirect injection diesel engines. At the lower end of 14:1, NOx emissions are reduced at a cost of more difficult cold-start. [6] See more 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 … 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 engine with a variable compression ratio was introduced in 2024. Variable … 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 engines are heat engines, … See more The static compression ratio discussed above — calculated solely based on the cylinder and combustion chamber volumes — does not take … See more • Mean effective pressure See more " - Compression ratio of diesel
