In a quick explaination... fuel inject is run by a computer, it takes information in from many sensors and adjusts things like timing, fuel and in some more elaborate systems it can even adjust the fuel for each individual cylinder....
There are a few main types of fuel inject
\
TBI- much like carbourator only computer controlled and in some ways much different.. sits on top of the intake

Multiport- has intake runners that are like a manifold only they themselves come directly off the fuel inject individually and have injectors for each runner

Chevy experimented with cross fire.. from anything I have read it didn't turn out too well... foget what it is

Umm anyone else wanna add to my list??? My knowledge is limited in this area

Not all FI systems are electronic. Mechanical FI came first.

There are also older forms of mechanical fuel injection. These work similarly to carbs but use engine vacuum and throttle activation to adjust the amount of fuel injected into the port. These can be found on feulie late 50's chevys (corvettes, belairs) Foreign cars (porsches, volkwagen)and race cars-where they're tuneability and power production were wanted. They were produced by companies such as Bosche, Hilborn, Rochester & others. Some of the stack-type racing mechanical systems are being converted to electronic injection by a couple of companies.

either way they all just mix air and gas-- and try to make some power doing it.
