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.

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.

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.

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.

What is a Combustion Engine?

• Combustion engine is an engine in which
  combustion of fuel occurs with an oxidizer in a
  combustion chamber

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

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.

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.

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.
