Fuel Feed System

UNDER THE HOOD

I'll talk about the type of fuel feed system on which a Petrol engine works 


well there r two types of fuel feed system for the engine


1: Carburetor
2: EFI (Electronic Fuel Injection)


Carburetor:-
                       A carbuetor is a device which mixes fuel with the air going in to the cylinder through  the intake manifold.In a carbureted engine the intake manifold is filled with air and fuel which is drawn in the cylinder when the valves open,the intake stroke of the piston pulls the air/fuel mixture inside the cylinder.This is what a carburator looks like

This is a Normal Carburetor it is located below the Air cleaner and what ever the company a all normal Carburetor look like this.Usually if it looks Different it may have a vacuum advance unit attached to it so if u take that away it looks like this. This is the tiny thing which has been driving the cars for nearly a Century.Its Technology is still being made because of old cars in the world but they r now more advanced and more powerful then there predecessor. A Modified Carburetor looks like this 

This is a Serial Intake Carburetor of a 4 Cylinder Engine


EFI:-
          Electronic Fuel Injection consist of different parts and components.Why is it dominating now a days is because it provide more fuel efficiency,uses less fuel and provide better Throttle Response.How?! Because it injects the required amount of fuel according to the amount of air being drawn in the cylinder and its know that because of the Sensors which r constantly giving output signal to the ECU(Electronic Control Unit) which is controlling the Injectors

 A Common Fuel Injector Rail with Injectors 


Note : The EFI system has nothing to do with the Ignition System mostly people think that if a car is EFI it is Distributorless , No ! An EFI car can have a distributor ( A Device used to distribute the high Voltage to ignite the Air/Fuel Mixture in each cylinder) .

I will Talk about then in detail later on ! 
Hopefully this was helpful !
