A combustion reaction occurs when a fuel and oxidant react, releasing heat or heat and light. The fire triangle represents the three elements needed for combustion - oxygen, heat, and fuel. Activation energy is the minimum amount of energy needed to initiate a chemical reaction like combustion. A combustion engine works by using combustion reactions of fuel and air to power the engine. NASCAR engines differ significantly from street car engines and are optimized for power and performance through specialized design choices. Injecting nitrous oxide into an engine allows it to produce more power by making more oxygen available during combustion to support additional fuel. Michael Waltrip was disqualified from a NASCAR race for illegally using addictive fuel to boost the performance of his engine through enhanced combustion

3. What is a combustion reaction? A combustion reaction takes place when a fuel and an oxidant react, ,making heat or heat and light. The most familiar form of combustion reaction is flame, with explosions being an even faster form of combustion reaction. A combustion can happen at a wide range of speeds, and can occur in many different environments. http://www.scsv.nevada.edu (http://en.wikipedia.org/wiki/Combustion)

4. What is the Fire Triangle? Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually form a fire. http://en.wikipedia.org/wiki/Fire_triangle

5. What is Activation Energy? The energy needed to get a reaction started 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. http://en.wikipedia.org/wiki/Activation_energy

6. Why is Heat/Energy a Necessary Part of the Fire Triangle? Without sufficient heat a fire cannot begin, and it cannot continue. Without the fuel a fire will stop and not continue The amount of energy produced by the reaction is higher than the quantity of energy requested to start it. http://en.wikipedia.org/wiki/Fire_triangle(http://pespmc1.vub.ac.be/macroscope)

7. How is the Cook top of your Stove a Real-Life Example of Fire Triangle? The cook top is related to your stove, simply because, when you start the stove, it has gas as the fuel, and oxygen surrounding it. So all it does is start a spark then ignites.

8. What is a Combustion Engine? Combustion engine is an engine in which combustion of fuel occurs with an oxidizer in a combustion chamber http://en.wikipedia.org/wiki/Combustion--->(http://www.physics.byu.edu/faculty/rees/360)

9. How does a combustion engine work? Fluids and heat gets the gears running to pump the engine so it would run perfectly. While the air is pumping out from the holes of the engine http://www.howstuffworks.com/engine.htm--->(http://media.photobucket.com/image/combustion%20engine/silverbeam/CSM%20Blog/EngineCutaway.jpg)

10. How are NASCAR engines different from a street car engines? There is virtually nothing similar between a NASCAR engine and a street car engine. They use a different engine blocks, pistons, alternators, suspension, electronics, etc. NASCAR engines even run on leaded fuel still. http://auto.howstuffworks.com/question588.htm-->(http://image.hotrod.com/f/9517342/hrdp_0803_01_z+chevy_nascar_engine+.jpg)

11. How Does Nitrous Oxide Help Engines Perform Better? By injecting nitrous oxide into an engine you are making more oxygen available during combustion. Because you have more oxygen, you can also inject more fuel, allowing the same engine to produce more power. www.nitrous.info/engine-preparation-for-nitrous->(http://www.pipedreamz.biz/images/dreamzycle_2.jpg))

12. Provide 1 document example of cheating in NASCAR in which something was done illegally to increase the combustion performance of the engine Cheating in NASCAR in which something was done illegally to increase the combustion performance of the engine Michael Waltrip used illegal addictive fuel and was disqualified for using it. http://nbcsports.msnbc.com/id/17204951-- ->(http://i.a.cnn.net/si/2007/writers/lars_anderson.jpg.)
