octane number, 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 knocking, and ...
Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3. Octane has many structural isomers that differ by the location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane), is used as one of the standard values in ...
Octane, chemically known as C 8 H 18, is an organic compound predominantly known for its role in fuel, particularly gasoline. It is an alkane with the molecular formula C 8 H 18. This saturated hydrocarbon plays a critical role in determining the quality of gasoline and its propensity to cause knocking or pinging in an engine.
Jun 4, 2021 · In short, an octane rating is a reading of the fuel’s stability. Regular fuel typically has an 87 octane rating, mid-grade fuel typically falls between 88-90, and premium fuel is typically...
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without undergoing pre-ignition. The higher the octane number, the more compression the fuel can withstand before detonating.
正辛烷 （octane）常簡稱 辛烷 ， 化學式 C 8 H 18 ，直连 烷烴 中的第八個成員。. 辛烷有18種 同分異構體 （若包括 立体异构体 则有24种），其中的異構物 2,2,4-三甲基戊烷 又稱 異辛烷 （isooctane），作為汽油引擎燃料使用時，震爆現象很低，因此被定為 辛烷值 100 ...
