GASOLINE OCTANE
Octane rating or octane number is a standard measure of the
performance of a motor or aviation fuel. The higher the octane
number, the more compression the fuel can withstand before
detonating. In broad terms, fuels with a higher octane rating are
used in high-compression engines that generally have higher
performance. In contrast, fuels with low octane numbers (but high
cetane numbers) are ideal for diesel engines. Use of gasolines with
low octane numbers may lead to the problem of engine knocking.
Gasoline is a volatile, flammable liquid obtained from the
refinement of petroleum, or crude oil. It was originally discarded
as a byproduct of kerosene production, but its ability to vaporize
at low temperatures made it a useful fuel for many machines.
Gasoline is primarily a mixture of two volatile liquids,
heptane and isooctane. Pure heptane, a lighter fuel, burns so
quickly that it produces a great amount of knocking in an engine.
Pure isooctane evaporates slowly and produces virtually no
knocking. The ratio of heptane to isooctane is measured by the
octane rating. The greater the percentage of isooctane, the less
knocking and the higher the octane rating. For example, an octane
rating of *7 is comparable to a mixture of *7% isooctane and *3%
heptane.Gasoline is one of the products derived from distilling and
refining petroleum. Compounds of organic lead were added to
gasoline in the past to reduce knocking in engines, but due to
environmental concerns this is no longer common. Other chemicals
are also added to gasoline to further stabilize it and improve its
color and smell in a process called "sweetening."
