• APPLICATION OF NITROUS OXIDE IN AUTOMOBILES

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.

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.

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 gt 2 N2 1 O2
• The additional oxygen being forced into the
  combustion chamber provides more potential power.

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.
