Gasoline Octane
Excerpt from Wikipedia:
An octane rating,
or octane number, is a standard measure of a fuel's ability to
withstand compression in an internal combustion engine without detonating.
The higher the octane number, the more compression the fuel can withstand
before detonating. Octane rating does not relate directly to the power output
or the energy content of the fuel per unit mass or volume, but simply indicates the gasoline's capability against compression.
Whether or not a higher octane fuel improves or impairs an
engine's performance depends on the design of the engine. In broad terms, fuels
with a higher octane rating are used in higher-compression gasoline engines, which
may yield higher power for these engines. Such higher power comes from the
fuel's higher compression by the engine design, and not directly from the
gasoline.
