  i don't quite understand after reading up on them. mind helping me?
  
  so to put it simply fuel injection is like spraying the petrol in a sort of mist form into the cylinder to combust whereas naturally/normally aspirated obtains the fuel by using a simple 'high volume-low pressure, low volume-high pressure' logic to get the petrol into the cylinder?

  N/A and Fuel Injection is totally different thing, you only compare Fuel Injection with Carburator and N/A with Turbo Charged and Supercharged....N/A is the nature of the engine and Fuel Injection is how the fuel is being delivered to power the engine.

  oh then what are other ways of injecting fuel into the engine?
  
  when you say nature of the engine, what do you mean?

  I think he meant Naturally Aspirated vs Forced Induction, not Fuel Injection?

  i is very noob lah but Forced Induction kinda means turbocharging or supercharging whereas naturally aspirated is just as it is.

  N/A stands for Naturally Aspirated...that means no turbocharging or supercharging the engine sort of breath on its own
