How ATV

’s Work Essay, Research Paper

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 ATV.s 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. ATV.s are also built to handle a lot of

stress and abuse. ATV.s 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, ATV.s also provide power and speed. There are also

amphibian ATV.s that float and go like a boat. ATV.s were first .work.

vehicles for telephone and electrical linemen and other types of people.

They used the ATV.s to get from one pole to another that went over

difficult terrain where 4×4 trucks could not go.

Second, you do not need a special permit or driver.s 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

company.s 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. ATV.s are

.Off-road. machines. There is also safety gear to protect you from harm.

These accessories include helmets, gloves, boots, chest protectors and so

on.

Third, ATV.s 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 time.s sake I have only listed

a few of the most popular ones. ATV.s 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.

(Microsoft Encarta 96 Internal Combustion Engine)

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

airbox to see if that.s where the trouble is. If there is water in the spark

plug dry it off and set it aside. Dry with a cloth, if possible. If the air filter

is wet ring it out. Step two is if it.s a four stroke, turn off the key and kick

the water out. Watch it blow out the exhaust and cylinder head. Step three

is to drain the float bowl. (If you suspect that water got in the tank )Which

is very hard, set it on it.s w
