It is the modern technology used in automobiles to

increase the power by injecting nitrous oxide into the

cylinder.

Nitrous oxide injection technology in automobile is a di

fficult technology to understand, though it is the easiest

and most cost effective performance modification.

Nitrous oxide engine is an engine in which the oxygen

required for burning the fuel stems from the

decomposition of nitrous oxide(N2O) rather than air.

Nitrous oxide, also known as dinitrogen oxide or

dinitrogen monoxide with chemical formula N2O.

It is commonly known as laughing gas.

Under room conditions it is a colourless non-flammable

gas, with a pleasant slightly sweet odour.

Nitrous Oxide and fuel are injected in to the intake manifold.

Nitrous cools the intake air.

Nitrous Oxide dissociated in to Nitrogen and Oxygen at 5250 F.

2 N2O ==> 2 N2 + 1 O2

The additional oxygen being forced into the combustion chamber provides more potential power.

TYPES OF NITROUS SYSTEM

There are two main types of nitrous system

DRY SYSTEM The N2O is injected into dry air (without fuel)

upstream in the manifold and it is then mixed withfuel at the injectors. The extra fuel required tomaintain the burn balance from Lean to Rich isdelivered by the injectors. The primary part of theintake is kept dry of fuel.

WET SYSTEM The fuel and Nitrous are mixed and introduced

together to the primary part of the intake. Thissystem produces slightly more power than dry butcannot be applied to an engine with a dry intaketypically most fuel injected engines.

offers more power-per-dollar than all known

ability to provide instant power.

power level can be varied by changing jets.

unlike cylinder heads and cams etc., the system can

be transferred from vehicle to vehicle.Nitrous systems can increase power by 0.5 hp (0.37 kW) to 3,000 hp (2,200 kW), depending on the engine type and nitrous system type.

Overheating of cylinder leads to explosion. Liquid nitrous will cause severe and permanent

frostbite damage to skin. Inhalation of nitrous oxide can cause suffocation and

immediate death. The nitrous system is designed to operate at 1100 psi

and exceeding that pressure can cause the engine to become too lean and cause extensive engine damage.

If a stock fuel system cannot supply enough fuel to the engine, the mixture will become too lean and severe engine damage will occur.

Activating the nitrous oxide system may cause an explosion on engine start-up.

This technology has been implemented in sport

vehicles since it has the ability to provide instant power

whenever needed. Within few years the use of nitrous

oxide in vehicles will be implemented in commercial

vehicles also.
