Nascar & Combustions

  1. 1. NASCAR & Chemical Reactions! By Rajiv Mishra
  2. 2. Chemical Reactions <ul><li>Combustion </li></ul><ul><li>Acid Base </li></ul><ul><li>Decomposition </li></ul><ul><li>Single Displacement </li></ul><ul><li>Double Displacement </li></ul>
  3. 3. What is Combustion Reaction? <ul><li>Chemical change that is the oxidation with the production of heat and light. </li></ul><ul><li>These reactions are endothermic and require constant energy input from the combustion reactions. </li></ul>
  4. 4. The Fire Triangle <ul><li>The fire triangle or combustion triangle is a simple model for understanding the ingredients necessary for most fires. </li></ul>
  5. 5. Activation Energy <ul><li>Minimum energy required to start a chemical reaction. </li></ul>
  6. 6. Why is the Fire Triangle important? <ul><li>The combination of Heat, oxygen and fuel is very dangerous and can cause a fire almost instantaneously, caused by this very ‘chain reaction.’ </li></ul>
  7. 7. How is the cook top of your stove a real life example of fire triangle? <ul><li>The cook top of a stove uses fuel, oxygen and heat in order for a fire to develop. </li></ul>
  8. 8. What is a Combustion Engine? <ul><li>The internal combustion engine or an ‘ICE’ is an engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber. </li></ul>
  9. 9. How does it work? <ul><li>In a ICE the expansion of the high temperature and pressure gases, which are produced by the combustion, directly applies force to a movable component of the engine (pistons or turbine blades) and by moving it over a distance, generate useful mechanical energy. </li></ul>
  10. 10. NASCAR Engines and 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 more than 300 horsepower. </li></ul><ul><li>into the cylinders, especially at high speeds (see How Camshafts Work for more details). </li></ul><ul><li>The intake and exhaust are tuned and tested to provide a boost at certain engine speeds. They are also designed to have very low restriction, and there are no mufflers or catalytic converters to slow the exhaust down either. </li></ul>
  11. 11. Nitrous Oxide <ul><li>Nitrous Oxide, well known in the streets as Nos/Nitro increases the horsepower. </li></ul><ul><li>This Oxide is very dangerous and very flammable and uses a lot of gasoline when used in a car. </li></ul>
  12. 12. Cheating in NASCAR <ul><li>In general, cheaters use three methods to make their cars go faster: They improve its aerodynamics, increase the amount of oxygen that gets to the carburetor, or boost its fuel capacity. </li></ul><ul><li>http://www.stockcarracing.com/techarticles/general/scrp_0607_auto_race_cheating/index.html </li></ul>
