octane

listen to the pronunciation of octane
English - English
Any of the eighteen isomeric aliphatic hydrocarbons (C8H18) found in petroleum, especially an iso-octane 2,2,4 trimethyl-pentane; they are used as fuels and solvents
An hydrocarbon of the paraffin series It is liquid at ordinary atmospheric conditions, although small amounts may be present in the gas associated with petroleum
Octane is a chemical substance that exists in petrol or gasoline and that is used to measure the quality of the fuel. high octane fuel for cars. see also high-octane. a type of hydrocarbon that is in fuel and is used as a measure of its quality (octo ; because it has eight carbon atoms)
A number that indicates the anti-knock quality of automotive gasolines
A flammable liquid hydrocarbon found in petroleum Used as a standard to measure the anti-knock properties of motor fuel
Any of the eighteen isomeric aliphatic hydrocarbons (C{8}H{18}) found in petroleum, especially an iso-octane 2,2,4 trimethyl-pentane; they are used as fuels and solvents
The most important is a colorless, volatile, inflammable liquid, found in petroleum, and a constituent of benzene or ligroin
Any one of a group of metametric hydrocarcons (C8H18) of the methane series
{i} unit of quality measurement in automobile gasoline; hydrocarbon with eight carbon atoms
Describes the grade of gasoline and its resistance to engine knock
any isomeric saturated hydrocarbon found in petroleum and used as a fuel and solvent
This is a measure of a fuel's resistance to detonation (See Detonation) The higher the number, the better the fuel Typical unleaded regular octane ratings range from 86 to 88 Premium grade unleaded fuels start around 89 and go as high as 93 or 94 By comparison, leaded premium fuels of a decade ago often started at 95 and went to over 100 The octane rating of gasoline can be boosted by additional refining and/or adding "octane boosting" chemicals such as benzene, alcohol or tetraethyl lead Lead is a great octane booster but it ruins catalytic converters and oxygen sensors Because of this, use of leaded fuel in 1975 and later model cars is a no-no

octane number
a measure of the antiknock properties of an automobile fuel; isooctane having an octane number of 100, a fuel with the same antiknock properties as a mixture of 90% isooctane and 10% heptane having an octane number of 90
octane numbers
plural form of octane number
octane number
a measure of the antiknock properties of gasoline
octane number
A numerical representation of the antiknock properties of motor fuel, compared with a standard reference fuel, such as isooctane, which has an octane number of 100. Also called octane rating
octane rating
(Otomotiv) A method of rating gasoline by measuring its ability to resist knocking, or pinging, in internal combustion engines. Engines with higher compression ratios require higher octane gasoline
high-octane
having a high octane number, good anti-knock characteristics; used in high performance vehicles
high-octane
high powered, energetic, forceful or dynamic
iso-octane
any isomer of octane except the normal, straight-chain one; especially 2,2,4-trimethylpentane
research octane number
An octane number, used by the American Society for Testing and Materials to estimate the antiknock characteristics of a fuel at low engine speeds
high-octane
vigorously energetic or forceful; "a high-octane sales manager"; "a high-octane marketing plan"; "high-powered executives"; "a high-voltage theatrical entrepreneur"
