WHAT IS A COMBUSTION REACTION?

A combustion is a chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species.

WHAT IS THE FIRE TRIANGLE?

The triangle illustrates a fire requires three elements: heat, fuel, and an oxidizing agent which is usually oxygen in many cases.

WHAT IS ACTIVATION ENERGY?

It’s the energy that an atomic system must acquire before a process can occur.

WHY IS HEAT/ENERGY A NECESSARY PART OF THE

TRIANGLE?

Heat is a necessary part of the triangle because without heat, the fire can not begin nor cant it continue.

HOW IS THE COOK TOP OF THE STOVE, A REAL LIFE EXAMPLE

OF THE FIRE TRIANGLE?

The stove is a real life example of the fire triangle because the stove needs heat, fuel, and oxygen in order for it to work.

WHAT IS A COMBUSTION ENGINE?

It is the engine in which the combustion of a fuel occurs with an oxidizer.

HOW DOES A COMBUSTION WORK?

A fuel such as gasoline fills the chamber and then it is ignited by a spark plug.

HOW ARE NASCAR ENGINES DIFFERENT FROM STREET ENGINES THAT ALLOW THEM TO OPERATE AT MUCH HIGHER

SPEEDS?

The displacement of NASCARS is large 358 cubic inches. Not many cars have engines this big, but the ones that do usually generate well over 300 horsepower.

They have high intensity programmable ignition systems so the spark timing can be customized to provide the most possible power.

HOW DOES OXIDE HELP ENGINES PERFORM BETTER?

Nitrous oxide improves performance even more. When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air.

When you heat nitrous oxide to about 570 degrees F (~300 C), it splits into oxygen and nitrogen. So the 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, allowing the same engine to produce more power.

GLENN DUNNAWAY

http://static.howstuffworks.com/gif/1993-nascar-results-1.jpg

Glenn Dunnaway won the race by three laps. But in further inspection, but it turned out the rear springs on the Ford were an improver. Dunnaway was disqualified form the race and Jim Roper was declared the winner instead.
