Nitrous oxide,commonlyknownas

laughing gas andnozz,

isa chemical compound

with the formulaN2O.

At room temperature, it

isa colorlessnon-

flammable gas, witha

pleasant, slightlysweet

odourand taste.

PRINCIPLE

The objective ofnitrous oxide is

to make more horsepower.Nitrous oxide comprises one-

part oxygen and two-part

nitrogen. This has a much

higher percentage of oxygen

than that found in the

atmosphere and, because of this

the additional oxygen being

forced into the combustion

chamber provides morepotential power. The additional

power cannot be obtained

safely without enriching the

amount of fuel in the

combustion chamber.

MAITAINING THE OPTIMUMAIR-FUELRATIO

The internal-combustionengine isbasicallyalargeairpumpand itsability topumpair isoneof the factors,whichdeterminehowmuchpower it canproduce.Air

containsoxygenandby drawing more oxygen into thecombustion chamber, more power will be produced.

Inorder toachieveefficient combustion, theairneeds tobemixedwith fuel in the correct ratio.Thestochiometric(chemically correct) ratio is forbasic gasoline is14.7

parts air to 1 part of fuel.

Greaterquantitiesofoxygen canbedrawn into thecombustion chamberbysimply introducing nitrousoxide.Byweight, Nitrous contains 36% oxygen while air has

only 23%. A chargeofnitrousoxide is capableofburning muchmore fuel than theequivalent amount of

air.


6/18

Because nitrous is more oxygen-rich than air, the

recommended air fuel ratio becomes 9.5 parts ofnitrous to 1 part of fuel (9.5:1). That means when

oxygen-rich nitrous is introduced additional fuel must

also be supplied in order to maintain the optimum

ratio Without the additional fuel the mixture would

become dangerously lean - circumstances that willalmost always lead to severe and expensive damage of

engine parts.

NITROUSSTORAGE For racing purposes, nitrous oxide is usually contained in

an aluminium cylinder; available in a variety of sizesranging from 2.5 lbs to 20 lbs. While retained in thecylinder the nitrous is in a liquid form and held underhigh pressure. When it is released from the cylinder intothe intake tract its physical state changes from a liquidto a gas. This transformation occurs as the nitrous is

released from an area of extreme pressure (thealuminium cylinders are pressurized to approximately1000 P.S.I.) into the vacuum of the intake manifold. Thischange in state is usually referred to as the nitrousboiling.

DrySystem

TheN2O is injected into dry air(without fuel)

upstream in themanifoldand it is thenmixed with fuel

at the injectors.Theextra fuelrequired tomaintain the

burnbalance from Lean to Rich isdeliveredby the

injectors. Theprimarypart of the intake iskept dryoffuel.

Wet System

The fueland Nitrous are mixed and introduced

together to the primary part of the intake.This

systemproducesslightlymore power than dry but

SAFETYASPECTS

One of the most important aspects ofkeeping an engine

healthy when using nitrous oxide is to ensure it operates

at the proper air/fuel ratio. Running too lean can cause

detonation, resulting in damaged engine parts. Running

too rich can also harm performance and destroy engine

parts, too. Once calibrated, they'll inject the properamount of fuel with the nitrous system to maintain the

correct air/fuel ratio.

NOS should only be activated when the position of the

throttle is wide open failing which can lead to

catastrophic effect which may lead to the whole

automobile exploding causing even fatal injuries. This

however is taken care by the solenoid provided.

The nitrous system is designed to operate at 1100 psiand exceeding that pressure can cause the engine tobecome too lean and cause extensive engine damage.

Ifa stock fuel system cannot supply enough fuel to theengine, the mixture will become too lean and severeengine damage will occur.

OTHERAPPLICATIONS

Rocket motors

Nitrous oxide can be used as an oxidizer in a r ocketmotor. This has the advantages over other oxidizers thatit is non-toxic and, due to its stability at roomtemperature, easy to store and relatively safe to carry on

a flight.In medicine

Nitrous oxide can also be used to dull the sensation ofpain, even if the inhaler were still semi-conscious, and soit came into use as an anesthetic, particularly by

dentists, who do not typically have access to theservices of an anesthesiologist and who may benefitfrom a patient who can respond to verbal commands.
