Combustion Reactions

  1. 1. Combustion reactions By: Sana Mohammed
  2. 2. Different types of chemical reactions <ul><li>There are 6 types of chemical reactions </li></ul><ul><li>Combustion </li></ul><ul><li>Synthesis </li></ul><ul><li>Decomposition </li></ul><ul><li>Single displacement </li></ul><ul><li>Double displacement </li></ul><ul><li>Acid-Base </li></ul><ul><li> </li></ul><ul><li> </li></ul>
  3. 3. Combustion Reaction <ul><li>Burning of Complex sequence of exothermic chemical reactions between a fuel. </li></ul><ul><li>http:// = en&defl = en&q = define:Combustion+reaction&ei =wLxsS6WGH5CANvG0yNgE&sa= X&oi = glossary_definition&ct = title&ved =0CAcQkAE </li></ul><ul><li> </li></ul>
  4. 4. Fire Triangle <ul><li>The fire triangle is mainly the three main things oxygen heat and fuel. </li></ul><ul><li>http:// </li></ul><ul><li>http:// = en&defl = en&q = define:Fire+triangle&ei =Fr5sS73fBY-INLHm7MoE&sa= X&oi = glossary_definition&ct = title&ved =0CAcQkAE </li></ul>
  5. 5. Activation Energy <ul><li>The energy that should be acquired before a process can occur. </li></ul><ul><li> </li></ul><ul><li>http:// = en&defl = en&q = define:activation+energy&ei =zL5sS-G9BorINZLq3NYE&sa= X&oi = glossary_definition&ct = title&ved =0CAcQkAE </li></ul>
  6. 6. Why is heat a necessary part of the fire triangle <ul><li>Without energy in the form of heat the fire cannot heat unburnt fuels. </li></ul><ul><li> </li></ul><ul><li>_archive/en/june2007/images/HEAT_WAVE_072605.jpg </li></ul><ul><li>http:// </li></ul>
  7. 7. Cook top of your stove <ul><li>The cook top of your stove is an example because we need heat and fuel to cook food. </li></ul><ul><li> </li></ul><ul><li>/AAAAAAAABns/X61AauN3_ug/s400/CookingFood.jpg </li></ul>
  8. 8. Combustion Engine <ul><li>The combustion of a fuel occurs with air </li></ul><ul><li> </li></ul><ul><li>=define:Combustion+Engine&ei=88FsS92wEor4NcbtsdAE&sa </li></ul><ul><li>=X&oi=glossary_definition&ct=title&ved=0CAcQkAE </li></ul>
  9. 9. How does a combustion engine work? <ul><li>The air enters the engine and helps it work faster and better. </li></ul><ul><li> </li></ul><ul><li>http:// </li></ul>
  10. 10. NASCAR engines and street car engines <ul><li>The engines are of a better quality and can be used for a longer period of time. While street car engines can take in only a certain amount of time. </li></ul><ul><li> </li></ul><ul><li>commons/thumb/0/0a/Gtp_sports_cars.jpg/300px-Gtp_sports_cars.jpg </li></ul>
  11. 11. Nitrous Oxide <ul><li>Nitrous oxide has another effect that improves performance even more. When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air. When you reduce the intake air temperature, you increase the air's density, and this provides even more oxygen inside the cylinder. </li></ul><ul><li> </li></ul><ul><li> </li></ul><ul><li>Concept-Nitrous-Oxide-Canisters-and </li></ul><ul><li>-Custom-Stereo-System-1280x960.jpg </li></ul>
  12. 12. Examples of cheating in NASCAR <ul><li>NASCAR inspectors, preparing to do tests on horsepower numbers following Saturday's Nationwide race at Michigan International Speedway, found magnets under the gas pedals on the two Gibbs Toyotas. </li></ul><ul><li>Tony Stewart, making his last Nationwide start for the Gibbs team, finished third in the No. 20, and 18-year-old rookie Joey Logano was seventh in the No. 18. The race was won by  CarlEdwards  in a Ford. </li></ul><ul><li>Toyota  has won 15 of 25 races this season in Nationwide, and all but one came in a Camry fielded by Gibbs. The exception was JGR driver Kyle Busch's victory at Charlotte in May in a car fielded by Braun Racing. </li></ul><ul><li>In the face of such domination, last month NASCAR ordered the Toyota Nationwide teams to use a smaller spacer to cut about 15 horsepower in their motors. </li></ul><ul><li>The incident Saturday was apparently an effort to keep the current numbers from looking too strong in the latest test. </li></ul><ul><li>&quot;In our post-race inspection — yesterday was the day we were going to chassis dyno cars — our inspectors discovered some shims that were placed on the gas pedal stop,&quot; Robin Pemberton, vice president of competition for NASCAR, said Sunday. &quot;It was magnets that were about a quarter-inch thick that prevented the accelerator from going 100 percent wide open. </li></ul>,2933,405301,00.html december/nascar500jpg.jpg
