The compression ratio of an internal-combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its largest capacity to its smallest capacity. It is a fundamental specification for many common combustion engines. In a piston engine, it is the ratio between the volume of the cyl...

The ratio between the combined volume of a cylinder and a combustion chamber when the piston is at the bottom of its stroke, and the volume when the piston is at the top of its stroke. The higher the compression ratio, the more mechanical energy an engine can squeeze from its air-fuel mixture. Higher compression ratios, however, also make detonatio...

The compression ratio indicates how much of a volume change the fuel-air mixture experiences inside the cylinders of an engine due to the moving pistons. In general, the higher this ratio is, the more powerful an engine of a certain displacement will be.

The numerical ratio of the decibel increase in input level of a compressor (above the threshold) that produces a one decibel increase in output level. Example: If the increase in input level is 5 dB for every 1 dB increase in output, the compression ratio is 5:1. (WW)

The ratio of compression, in the cylinder of an aero engine. Determined by the formula (r + R)/r, where 'r' is the compression space in the cylinder when the piston is at Top Dead Centre and 'R' is the volume swept by the piston in the cylinder.

The volume of the combustion chamber and cylinder when the piston is at the bottom of its stroke, divided by the volume of the combustion chamber and cylinder when the piston is at the top of its stroke. Higher compression ratios tend to increase engine efficiency.

The ratio of the volume within an engine cylinder when the piston is at the bottom of its stroke, compared to the volume in the cylinder when the piston is at the top of its stroke. The higher the ratio, the more compression during combustion and the more powerful the engine. Eg- 8:3:1
