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 difficult 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.

INTRODUCTION

Discovered by Joseph Priestley in 1772. More studies was done by Humphry Davy in the 1790s

and realised that it can be use as an anaesthetic, particularly by dentists.

HISTORY

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.

ABOUT NITROUS OXIDE

What happens on burning N2O?

When a mole of nitrous oxide decomposes, it releases half a mole of O2 molecules (oxygen gas), and one mole of N2 molecules (nitrogen gas). This decomposition allows an oxygen concentration of 33% to be reached.

It can be used as an oxidiser in rocket engine.

It is used in automobiles to increase the power.

It is used in surgery and dentistry for its anaesthetic and analgesic effects.

USES

Use as an oxidizing agent Supports combustion better than regular air Molecule breaks at low temperature leaving

pure oxygen and nitrogen in the engine. Boosts horsepower up to 50%.

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 with fuel at the injectors. The extra fuel required to maintain the burn balance from Lean to Rich is delivered by the injectors. The primary part of the intake is kept dry of fuel.

WET SYSTEM The fuel and Nitrous are mixed and introduced

together to the primary part of the intake. This system produces slightly more power than dry but cannot be applied to an engine with a dry intake typically most fuel injected engines.

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.

PRINCIPLE

Mechanism N2O injected N2O changes state

to gas Cools intake

charge, allowing for more air/fuel mixture.

As the cylinder heats from compression/combustion, O breaks away from N2O

offers more power-per-dollar than all known alternatives. 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 oxide system can be easily replaced. There are many other uses for Nitrous Oxide

including propellant in whipped cream and an oxidizing agent in racecars

ADVANTAGES OF NITROGEN OXIDE SYSTEM

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.

Limitations

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.
