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 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 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
1 A colorless inflammable hydrocarbon found in petroleum and used as a solvent 2 Canada's leading trade magazine for the service station industry 3 London-based independent petrol brand acquired by VIP in 1965 4 Popular abbreviation for Octane Number (or RON) as in "99 Octane"
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
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
(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
vigorously energetic or forceful; "a high-octane sales manager"; "a high-octane marketing plan"; "high-powered executives"; "a high-voltage theatrical entrepreneur"
You can use high-octane to emphasize that something is very exciting or intense. a high-octane performance. high-octane petrol is of a very high quality
