INRODUCTION
It is the modern technology used in automobiles to increase the power by injecting nitrous oxide into the cylinder.
HISTORY
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.
ABOUT NITROUS OXIDE
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.
USES
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.
PRINCIPLE
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.
Limitations
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.
CONCLUSION
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.
