Its hard for me to comment on post related to Engineering cos its not just my thing.
However i appreciate the effort put into this.
Is there any particular reason why the carburetor is being replaced by the fuel injector...., they do the same thing i think.
The major reason the injector replaced the carburetor is because the injector can be controlled by the vehicle's computer - the E.C.U. So, its more like saying the carburetor is analog while the injector is digital 😁.
The ability to control the injection of fuel into the engine helps to control emissions and also improves fuel economy.
Hope i made sense.
