Halogens

Halogen compounds - those containing fluorine, chlorine, bromine or iodine are
generally associated with fire extinguishing.  The halogen has a strong
affinity for hydrogen or combinations of oxygen and hydrogen such as hyperoxy
or hydroxy radicals.  This removes the free radicals from combustion exactly
as if the hydrogen chain reaction had hit the cylinder wall.  It does not take
a lot to effectively stop combustion.

A small percentage of halogens "sprinkled" in a fuel - particularly a "boost"
fuel will make the effective diameter of a cylinder much smaller and
significantly raise the octane of the fuel.

As combustion continues, the Halogen oxidizes and re-releases the OxHx
compounds it has trapped.

Any chemical with Benzo in it contains a benzene ring.  The additional stuff
will be substituted for one or more of the rings hydrogens.  These substances,
when burned, will release first the subsituted particles and then decompose
the ring.  Keep in mind that using the Research Method of Octane Testing, the
research engine could not cause Benzene to detonate.

And Benzotrifluoride ( a benzene ring with a CF3 substitution ) ? - its an EPA
exempt solvent that blends with alcohol, ether and fuel.
