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.
What is octane rating? Octane rating is the measure of a fuel's ability to resist knocking or pinging during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In the U.S., unleaded gasoline typically has octane ratings of 87 (regular), 88â90 (midgrade), and 91â94 (premium).
