When real performance
enthusiasts think of nitrous oxide injection, one company springs to
mind: NOS - Nitrous Oxide Systems! NOS pioneered nitrous injection in
the 1970s, and today NOS powers more racers than any other nitrous
company. Only NOS has such a wide assortment of systems and
applications—just pick the power increase level you want, and NOS will
get you there with a complete kit, including all the plumbing, hardware,
and electronics you need. We’re also your source for NOS nitrous
accessories like bottles, bottle brackets, blankets, injection nozzles,
controllers and timers, and even illuminated purge valves for pure
intimidation.
Why Not Pure Oxygen?

The
simple and most relevant answer is because we couldn’t get enough into
the engine for it to be as effective as NOS / nitrous oxide. Air has
only 23.6% oxygen by weight, the rest is made up largely of nitrogen.
Although nitrogen does not aid the actual combustion process it does
absorb heat, as well as damping what would otherwise be a violent
explosion, rather than a controlled burn. When you add nitrous, it has
36% oxygen with the rest being nitrogen. So the more nitrous oxide you
add, the less percentage of nitrogen is available to absorb heat. That’s
one of the reasons why adding more nitrous increases the heat of
combustion very rapidly. If we were to add pure oxygen (which has been
tried), the percentage of nitrogen would progressively decline to a much
greater degree than with nitrous, as more and more oxygen was added.
Consequently an engine wouldn’t be able to handle much pure oxygen
before the increase in heat lowered the detonation level to unusable
levels. Furthermore, oxygen can only be ‘readily’ stored in a compressed
‘gaseous’ form, without being stored in a special cryogenic thermos
cylinder (a cylinder within a cylinder with a vacuum between the two
walls) and as a gas it loses the cooling effect that nitrous offers by
being available as a liquid. Adding the oxidiser as gaseous oxygen would
displace more air than adding nitrous in liquid form, resulting in a
lower total power capability. In other words; by using nitrous oxide we
can squeeze in more oxygen atoms in a more beneficial form, containing
substantial amounts of detonation suppressing nitrogen, than would be
the case with gaseous oxygen.
