Weboctane number, also called Antiknock Rating, measure of the ability of a fuel to resist knocking when ignited in a mixture with air in the cylinder of an internal-combustion engine. The octane number is determined by comparing, under standard conditions, the knock intensity of the fuel with that of blends of two reference fuels: iso-octane, which resists …
WebMay 22, 2024 · The compression ratio in a gasoline-powered engine will usually not be much higher than 10:1 due to potential engine knocking ( autoignition) and not lower than 6:1. Higher compression ratios will however make gasoline engines subject to engine knocking, caused by autoignition an unburned mixture, if lower octane-rated fuel is used.
