For the world to operate on a unified time platform, it is imperative to have all the major clocks on the globe synchronized to one single accurate/stable clock piloted by the atomic time for precision â master clock. And this is achieved by connecting all clocks to the master clock by a wave called the pilot carrier.
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 amount and location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (isooctane) is used as one of the standard values in the octane rating scale. Octane is a component of gasoline (petrol). As with all low molecular weight hydrocarbons, octane is volatile and very flammable.
Definitions. Reference Fuel â In the measurement of octane quality of gasoline a mixture of two hydrocarbons called iso-octane and normal heptane. Iso-octane is assigned an octane rating of 100, and normal heptane is assigned an octane rating of zero. A blend of 90% iso-octane and 10% n-heptane would have an octane rating of 90 octane. (R + M) / 2 â The average of Research Octane Number and Motor Octane Number; one measure of the combustion quality of gasoline.
