The 13 pages that link to Compression ratio, each with the reason it gives.

• Diesel engineRelated: High compression raises air temperature enough to ignite injected fuel.

• Data compressionRelated: It provides a practical size measure, though results depend on the chosen input and format.

• Octane ratingRelated: Higher compression increases pressure and temperature, making knock resistance more consequential.

• CompressorRelated: It quantifies the pressure increase a compressor stage must produce.

• Otto cycleRelated: This ratio is the main geometric parameter governing ideal Otto-cycle efficiency.

• Combustion chamberRelated: It links chamber size at ignition to pressure, temperature, and efficiency.

• Spark-ignition engineRelated: It influences efficiency and the mixture’s tendency to knock.

• Engine knockingRelated: Greater compression generally raises end-gas pressure and temperature, increasing knock tendency.

• Wankel engineRelated: It influences the Wankel’s efficiency, power, and resistance to knock.

• Diesel cycleRelated: It is a principal geometric input to ideal Diesel-cycle efficiency.

• Piston engineRelated: It describes how strongly the piston compresses the cylinder's charge before ignition.

• Reciprocating engineRelated: It affects the pressure and temperature reached before combustion in a piston engine.

• Pistonless rotary engineRelated: Rotary chamber geometry determines compression ratio and strongly affects efficiency.
