Shauns Combustion Powerpoint

  1. 1. Combustion reactions related to….NASCAR!!! By: Shaun Mujtaba
  2. 2. Different types of chemical reactions <ul><li>The different types of chemical reactions are: </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>Info: http://misterguch.brinkster.net/6typesofchemicalrxn.html </li></ul><ul><li>Pic: http://www.chemistryland.com/CHM130/IconChemicalReactions.jpg </li></ul>
  3. 3. What is a combustion reaction? <ul><li>A combustion reaction is a reaction in which a substance reacts with oxygen and heat is released. </li></ul><ul><li>Info: http://wiki.answers.com/Q/What_is_a_combustion_reaction </li></ul><ul><li>Pic: http://pictures.directnews.co.uk/liveimages/fire_901_18347392_0_0_7006845_300.jpg </li></ul>
  4. 4. A FIRE triangle <ul><li>A simple model for understanding the ingredients necessary for most fires. </li></ul><ul><li>Info:en.wikipedia.org/wiki/Fire_triangle </li></ul><ul><li>Pic:en.wikipedia.org/wiki/Fire_triangle </li></ul>
  5. 5. Activation energy <ul><li>The energy, in excess over the ground state, which must be added to an atomic or molecular system to allow a particular process to take place. </li></ul><ul><li>Info: http://www.answers.com/topic/activation-energy </li></ul><ul><li>Pic: http://www.studentsoftheworld.info/sites/family/img/27335_Electricity.jpg </li></ul>
  6. 6. Why is heat/energy necessary for a fire triangle <ul><li>Heat and energy are necessary for a fire triangle because its one of the main parts of the fire triangle. </li></ul>
  7. 7. How is the cook top of my stove a real life example of a fire triangle? <ul><li>It’s a real life example because of the FIRE! </li></ul><ul><li>Info: http://www.chinatraderonline.com/Files/home-appliance/Electrical-Burner/Electric-Double-Stove-13493538447.jpg </li></ul>
  8. 8. What is a combustion engine? <ul><li>An engine in which the combustion of a fuel, mostly fossil fuel, occurs with an oxidizer usually air in a combustion chamber. </li></ul>
  9. 9. How does a combustion engine work? <ul><li>An external combustion engine (EC engine) is a heat engine where an (internal) working fluid is heated by combustion of an external source, through the engine wall or a heat exchanger. The fluid then, by expanding and acting on the mechanism of the engine produces motion and usable work.The fluid is then cooled, compressed and reused (closed cycle), or (less commonly) dumped, and cool fluid pulled in (open cycle air engine </li></ul><ul><li>Info: http://wiki.answers.com/Q/How_does_an_external_combustion_engine_work </li></ul>
  10. 10. How are NASCAR engines different from street car engines? <ul><li>The displacement is large -- 358 cubic inches (5.87 liters). Not many cars have engines this big, but the ones that do usually generate well over 300 horsepower. </li></ul><ul><li>The NASCAR engines have extremely radical cam profiles, which open the intake valves much earlier and keep them open longer than street cars. This allows more air to be packed into the cylinders, especially at high speeds </li></ul><ul><li>Info: http://auto.howstuffworks.com/question588.htm </li></ul>
  11. 11. How does nitrous oxide help engines perform better? <ul><li>The injection of nitrous oxide into an engine means that more oxygen is available during combustion </li></ul><ul><li>Which basically means that cars can go faster without burning out. </li></ul><ul><li>Info: http://auto.howstuffworks.com/question259.htm </li></ul><ul><li>Pic: http://www.altecpetroleumgroup.com/images/glossary/nitrous%20oxide.jpg </li></ul>
  12. 12. When someone cheated in…… NASCAR!!!!!! <ul><li>On August 17, 2008 Joe Gibbs cheated!! </li></ul><ul><li>NASCAR officials found magnets on the accelerator pedals of the two Gibbs Toyotas, the Observer reported. Several sources said the magnets might keep the pedals from being fully depressed, which would limit the engines' output and distort data. </li></ul>
  13. 13. <ul><li>Info on that last slide: blog.al.com/blogoftomorrow/2008/08/nascar_cat... </li></ul><ul><li>Pic: http://static.howstuffworks.com/gif/2006-nascar-results-1.jpg </li></ul>
