How Does Nitrous Oxide
Work?
There are three points. First,
nitrous oxide is comprised of 2 parts nitrogen and one part oxygen (36% oxygen
by weight). When the nitrous oxide is heated to approximately 572oF
(on compression stroke), it breaks down and release extra oxygen, However, it is
not this oxygen alone which creates additional power, but the ability of this
oxygen to burn more fuel. By burning more fuel, higher cylinder pressures are
created and this is where most of the additional power is realized. Secondly, as
pressurized nitrous oxide is injected into the intake manifold, it changes from
a liquid to a gas (boils). This boiling affect reduces the temperature of the
nitrous to a minus .127 Degrees F. This "cooling affect" in turn
significantly reduces intake charge temperatures by approximately 60-75 Degrees
F. This also helps create additional power. A general rule of thumb: For every
10 Degrees F. reduction in intake charge temperature, a 1% increase in
power will be realized. Example: A 350 HP engine with an intake temperature drop
of 70 Degrees F, would gain approximately 25 HP on the cooling affect alone. The
third point, the nitrogen that was also released during the compression stroke
performs an important role. Nitrogen acts to "buff or dampen" the
increased cylinder pressures leading to a controlled combustion process.
Why Nitrous?
Nitrous oxide injection has
become a very popular option for today's performance enthusiast for several
reasons:
