There are three main types of fuel injection:
1. Throttle Body Injection, ie one or two huge injectors mounted in the throttle body - basically an electronically controlled carbeurettor. There were a few cars in the 80's with a setup like this (eg Magna) but I don't think any new cars use it.
2. Port Injection aka Multi-Point Injection, ie one injector mounted in/near each inlet port. The vast majority of EFI engines today use this.
3. Direct Injection, ie one injector mounted inside the combustion chamber (like a spark plug) which injects fuel at extremely high pressure just before ignition. Diesels have done this for decades but it's pretty new for petrol engines. Toyota have had it for a few years now, I think the 2JZ-FSE was released in the late 90's?
