2. INRODUCTION
• It is the modern technology used in
automobiles to increase the power by injecting
nitrous oxide into the cylinder.

3. 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.

4. 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.

5. 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.

6. NITROUS OXIDE SYSTEM IN
AUTOMOBILES
• WET SYSTEM
• DRY SYSTEM

7. 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.

17. ADVANTAGES OF NITROGEN
OXIDE SYSTEM
• 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.

18. 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.

19. 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.
