How ATV\'s Work

Thesis statement: All terrain vehicles are helpful and useful and I will
explain how they work and how to fix them in this paper.

Outline: Inn this paper I will discuss ATVís and general knowledge and
getting them wet. I also will discuss their origin and how they need care and
how to keep them doing good for a long time.

What is an ATV? It is an All Terrain Vehicle, also called three or
four wheelers. It is also called a quad or ATV. An ATV is built to go
where other vehicles cannot go. ATVís are also built to handle a lot of
stress and abuse. ATVís are virtually indestructible; however, they have a
few weaknesses and it is important to know and understand those few
weaknesses. You should always do a complete check of your ATV before
riding . Second, ATVís also provide power and speed. There are also
amphibian ATVís that float and go like a boat. ATVís were first ďworkĒ
vehicles for telephone and electrical linemen and other types of people.
They used the ATVís to get from one pole to another that went over
difficult terrain where 4x4 trucks could not go.

Second, you do not need a special permit or driverís license to drive
a ATV although special training is recommend by several manufacturers
and some even give seminars and free classes. I believe that some
companyís give cash back to people who take classes. I ,myself, have not
taken any of these classes. There are no age limits or restrictions because
these are not operated on public streets, roads or highways. ATVís are
ďOff-roadĒ machines. There is also safety gear to protect you from harm.
These accessories include helmets, gloves, boots, chest protectors and so
on.

Third, ATVís need some type of power plant to propel them. The types of
power plants that are most common are the two stroke engine and the four
stroke engine (A stroke is one movement of the piston Microsoft Encarta
96 Internal Combustion Engine). The general principle of the two-stroke
engine is to shorten the periods in which fuel is put into the combustion
chamber and in which the spent gases are exhausted to a small fraction of
the duration of a stroke instead of allowing each of these operations to
occupy a full stroke. In the simplest type of two-stroke engine, the poppet
valves are replaced by sleeve valves or ports (openings in the cylinder wall
that are uncovered by the piston at the end of its outward travel). In the
two-stroke cycle, the fuel mixture or air is introduced through the intake
port when the piston is fully withdrawn from the cylinder. The
compression then stroke follows, and the charge is ignited when the piston
reaches the end of this stroke. The piston then moves outward on the power
stroke, uncovering the exhaust port and permitting the gases to escape from
the combustion chamber.1 The four stroke model has four strokes instead
of two. The strokes are Intake, into which a mixture of gas and air are
pulled into the cylinder. Second, Compression, where the piston moves up
and the gases are compressed. The Third is power in which the spark plug
fires and ignites the compressed gases, And last is exhaust in which the
gases that were burned are expels through the exhaust then the procedure
repeats itself. The most common type of ATV (Three and Four wheelers)
Manufactures are Yamaha, Honda, Kawasaki, Hosquravana, Suzuki and
Polaris. There are several other brands but for timeís sake I have only listed
a few of the most popular ones. ATVís come in a variety of sizes and
powers. from a small 80cc to a huge two stroke 600cc! I own a 1989
Yamaha Breeze and have to repair it quite often. There are some simple
things to do that are cheap and will save money in the long run. For
example adding transmission fluid or crankcase oil could save hundreds at
a repair shop. Some times repairs get challenging as your quad (ATV) ages
it will need special care such as an oil change, Brake pads, spark plugs
ETC. You may even need to rebuild the engine. This involves a complete
stripdown. You generally replace the piston, rings and valve guide seals. If
you do a lot of water riding you should do maintenance more often. If you
should your quad drown out follow these four simple steps.

Step one is to pull the quad out of the water. Pop the lid off the
