Have you ever opened the hood of your car and wondered what was going on in there? Car engine can look like a big confusing jumble of metal, tubes and wires to the uninitiated.

You might want to find out what’s going on simply out of curiosity. Or maybe 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-in mean?

In this article we will discuss the basic idea behind the engine and then go into detail about how to fit all the pieces together, what can go wrong and how to increase performance.
The purpose of the gasoline car engine to convert gasoline into motion so that your car can move. Currently the easiest way to create motion from gasoline to burn the gasoline inside your engine. Thus, the internal combustion engine car engine – combustion takes place internally.

Two things to note:

* There are different kinds of internal combustion engine. Diesel engines are one form and other gas turbine engines. See also the section on Hemi engines, rotary engines and two-stroke engines. All have their own advantages and disadvantages.

* There is such a thing as an external combustion engine. A steam engine in old-fashioned trains and steam boats the best example of an external combustion engine. The fuel (coal, wood, oil, whatever) in a steam engine burns outside the steam engine to create, 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 less than equivalent external combustion engine. That’s why we can not see any cars from Ford and GM using steam engines.
