Have you ever opened the hood of your car and wondered what was going on in
there? A car engine can look like a big confusing jumble of metal, tubes and
wires to the uninitiated.
You might want to know what's going on simply out of curiosity. Or perhaps you
are buying a new car, and you hear things like "3.0 liter V-6" and "dual
overhead cams" and "tuned port fuel injection." What does all �of that mean?
��In this article, we'll discuss the basic idea behind an engine a�nd then go
into detail about how all the pieces fit together, what can go wrong and how
to increase performance.

�The purpose of a gasoline car engine is to convert gasoline into motion so
that your car can move. Currently the easiest way to create motion from
gasoline is to burn the gasoline inside an engine. Therefore, a car engine is
an internal combustion engine  combustion takes place internally.
Two things to note:
    * There are different kinds of internal combustion engines. Diesel engines
are one form and gas turbine engines are another. See also the articles on
HEMI engines, rotary engines and two-stroke engines. Each has its own
advantages and disadvantages.
    * There is such a thing as an external combustion engine. A steam engine
in old-fashioned trains and steam boats is the best example of an external
combustion engine. The fuel (coal, wood, oil, whatever) in a steam engine
burns outside the engine to create steam, and the steam creates motion inside
the engine. Internal combustion is a lot more efficient (takes less fuel per
mile) than external combustion, plus an internal combustion engine is a lot
smaller than an equivalent external combustion engine. This explains why we
don't see any cars from Ford and GM using steam engines.
Terms and conditions apply.

Only to someone who is in ignorance of the devices.
Something that can easily be learned, it's up to the individual to educate them 
selves on "What does this all mean".
The purpose of an internal combustion engine is to convert CHEMICAL energy in 
the form of heat into mechanical energy.
Do some research on "efficiency". You are in an area that it is very clear you 
are not very versed in."
