Catalytic Converter, The Automatic Exhaust System

Every car user knows little or something about their car’s exhaust system. This slide will put more light on it. Catalytic converters are pollution reducing units helps to eliminate danger of toxins contained in exhaust. It describes how it works, why it is essential, why engines make pollution, harmful gases produced by engines, tips to protect catalytic converters, how it is valuable, steps to reduce the risk of theft. I am sure it will help you out and do comment and like.

Catalytic Converter, The Automatic Exhaust System

  1. 1. Catalytic Converter: The Automotive Exhaust System
  2. 2.  Keeping the exhaust system in perfect condition is very vital for the vehicle users.
  3. 3.  The exhaust contains toxins that can be injurious hence a catalytic converter is invented to eliminate this danger.
  4. 4. It is very essential for: Fuel mileage Environment Safety of the driver
  5. 5. Why Engines Make Pollution??
  6. 6. Car engines run on: Gasoline Diesel Which are made from Petroleum
  7. 7.  Petroleum is made up of hydrocarbons which is formed when the tiny sea creatures rot down, heat up and get squeeze by layers of sea bed rocks.
  8. 8.  If you burn any kind of hydrocarbon with oxygen from the air, it will release energy along with CO2 & water along with other poisonous gases.
  9. 9.  And the gases emitted by a car engine include various poisonous gases like carbon monoxide & nitrogen oxides that cause smog.
  10. 10. What Is A Catalytic Converter?
  11. 11.  Catalytic converters are pollution reducing units.
  12. 12. How it works ?
  13. 13.  Within the catalytic converter a chemical reaction takes place in which noxious fumes are turned into less harmful matter.
  14. 14. A catalytic converter is a large metal box, having two pipes coming out of it.
  15. 15.  One of them is connected to the engine which brings hot polluted fumes from the engine’s cylinders & Second pipe is connected to the exhaust.
  16. 16.  When the gases blow over the catalyst, chemical reaction takes place, converting the polluted gas to some other gases that are safe enough.
  17. 17. HC CO NO2 H2O CO2 N2 Polluted Air Cleaned Air
  18. 18. The Culprits:
  19. 19. HC • This is in the form of unburned gasoline CO • Created by the combustion of gasoline NO2 • Produced when the heat of the engine forces N2 to combine with O2
  20. 20. The Winners:
  21. 21. Converted from the hydrocarbons CO2 & H2O Converted from the carbon monoxide CO2 Converted from the nitrogen oxide N2 & O2
  22. 22. What Makes A Catalytic Converter So Valuable ??
  23. 23. Precious metals like platinum, palladium and rhodium are used in catalytic converters to remove toxins from the engine. The price of these valuable metals are around hundreds of dollars .
  24. 24. Always park your vehicle in a locked garage or in well lighted areas.
  25. 25. If you are working at a factory, park in a fenced area..
  26. 26. If you are going for shopping, park close to the entrance of the mall.
  27. 27. If you find someone acting suspiciously around your vehicle, report it to the nearest police station.
  28. 28. Purchase a vehicle security system
  29. 29. Engrave your license plate on the converter to make it identifiable.
