What is combustion reaction?

A combustion

reaction is when

oxygen combines

with another

compound to form

water and carbon

dioxide. These

reactions are

exothermic,

meaning they

produce heat.

What is the fire triangle?

Fire triangle is a

simple model for

understanding the

ingredients

necessary for most

fires.

What is activation energy?

Activation

energy is the

minimum energy

required to start

a chemical

reaction.

Why is heat/energy a necessary part of the fire triangle?

Without heat, a

fire cannot

begin, and it also

cannot continue.

How is the cook top of your stove (not electric) a real-life of a fire triangle?

The cook top of

your stove needs

air, fuel, and heat

in order to make

a fire.

What is combustion engine?

External combustion engine is a heat engine where an (internal) working fluid is heated by combustion of an external source, through the engine wall or a heat exchanger. The internal combustion engine is an engine in which the combustion of a fuel (generally, fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber.

(in general) How is combustion engine work?

With an internal

combustion engine,

fuel is burned inside

the engine in what is

known as a combustion

chamber. The

combustion chamber is

an enclosed space

where the gasoline

goes. Once the gas of

the confined gasoline

expands, it produces

energy.

In term of combustion, how are NASCAR engines different from street car engines that allow them to operate at

much higher speed?

They are based on a

340 cubic inch V-8

engine design that

was produced in the

1960s. The actual

engine blocks and

heads are not made

from the original

tooling, they are

custom made race

engine blocks, but

they do have some

things in common

with the original

engines.

How does nitrous oxide help engines perform better?

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.

One documented example of cheating in NASCAR in which something was done illegally to increased the

combustion performance of the engine.

The news of Michael Waltrip cheating in

NASCAR. The officials found illegal

additives had been mixed in the fuel of his car All the crews try to do something

with the car to increase its

performance and are involved in some

degree of cheating and they know that

the maximum penalty is a fine and lose of points so they just try and go that extra mile hoping

that they don’t get caught.
