What is a Combustion Reaction? : 

What is a Combustion Reaction? Reference A combustion reaction takes place when a fuel and an oxidant react, producing heat or heat and light. The most common form of a combustion reaction is the flame, with explosions being an even faster form of combustion reaction. Combustion can happen at different speeds, and can happen in different environments. http://www.wisegeek.com/what-is-a-combustion-reaction.htm

What is a Fire Triangle? : 

What is a Fire Triangle? Reference http://ehs.sc.edu/modules/fire/01_triangle.htm http://www.wisegeek.com/what-is-a-combustion-reaction.htm The fire triangle represents three things that must be present to help each other to have combustion: fuel, an oxidizer, and heat. The oxidizer is a substance that produces the oxygen so that the fuel can be burned, and heat is the substance that sparks the combustion process.

Slide 4: 

What is Activation Energy? Reference A substantial amount of energy is needed for a chemical reaction to take place, due to the strength of the bonds that need to be broken. Activation energy is the energy that must be overcome in order for a chemical reaction to occur or the minimum energy required to start a chemical reaction. Heat, a physical factor, and adding an appropriate enzyme, a chemical factor, are two examples of factors that activate molecules. http://www.wisegeek.com/what-is-a-combustion-reaction.htm http://www.humanthermodynamics.com/activation-energy_op_800x547.jpg

Why is heat necessary to the fire triangle? : 

Why is heat necessary to the fire triangle? Reference Heat is the substance that sparks the combustion process. To initially start a fire it is necessary to apply heat to the fuel in the form of a flame or spark. This heat must raise the fuel to its ignition temperature. Continued heat is then needed to keep the fuel at its ignition temperature and keep the fire going. This heat is usually supplied by the fire itself. http://en.wikipedia.org/wiki/File:Fire_triangle.svg http://www.wisegeek.com/what-is-a-combustion-reaction.htm

Your Stove and the Fire Triangle : 

Your Stove and the Fire Triangle Reference A cook top stove is a real-life example of the fire triangle. The fuel is the gas coming into the stove. The oxygen used is from the air around you, and the heat used is from the pilot light inside your stove. When we turn the knob on the stove we ignite it, and we can also control the size of the flame, or fire. http://www.survivaltopics.com/survival/fire-tetrahedron/

What is a Combustion Engine? : 

What is a Combustion Engine? Reference http://inventors.about.com/library/inventors/blinternalcombustion.htm An internal combustion engine is any engine that operates by burning its fuel inside the engine. The most common combustion engine type is gasoline powered. Engines typically can only run on one type of fuel. http://www.google.com/search?sourceid=navclient&ie=UTF-8&rlz=1T4ADBR_enUS237US238&q=engine+pictures

Slide 8: 

How Combustion Engines Work Reference A combustion engine fueled by gas fills a chamber and then is ignited by a spark plug causing a small explosion. The superheated gas created by the explosion pushes a piston which drives a crankshaft connected to the axel and drives the car forward. http://www.wisegeek.com/how-does-an-internal-combustion-engine-work.htm

NASCAR Engines vs. Street Car Engines : 

NASCAR Engines vs. Street Car Engines Reference NASCAR engines are different from street car engines because they have larger displacements, intake valves that open earlier and keep them open longer. They have carburetors that let in huge volumes of air, fuel and high ignition systems. http://www.howstuffworks.com/question588.htm

Slide 10: 

Nitrous Oxide and Engine Performance Reference When you heat nitrous oxide it splits into oxygen and nitrogen. So an injection of nitrous oxide into an engine means that more oxygen is available during combustion. Because you have more oxygen, you can also inject more fuel and the engine produces more power. Nitrous oxide is an easy way to cause a horsepower boost to any gasoline engine. http://auto.howstuffworks.com/question259.htm

Slide 11: 

Illegal Combustion Performance and NASCAR Reference NASCAR drivers were disqualified for adding a jet fuel like substance .The substance was found during Sunday's inspection. Adding the substance, described by NASCAR as an oxygenate, would boost the octane in the fuel, and making the engine run better at higher horsepower. http://cbs2chicago.com/sports/NASCAR.cheating.Toyota.2.279820.html
