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, and higher compression ratios permit the same combustion temperature to be reached with …

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 relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the pis…
Web21 okt. 2024 · The compression ratio is determined by the compression algorithm and the settings used. Higher compression ratios can be achieved by using lossy compression algorithms, which sacrifice some image quality for smaller file sizes.
