Fuel Injector


Fuel injectors are electronically controlled devices that dispense a fuel mist into a combustion engine.


When the plunger in a fuel injector rises, a valve is opened, and the fuel is sent through the spray tip either into the intake manifold, or directly into the engine's cylinder.


Fuel injectors can deliver precise amounts of fuel at specified time intervals.





Top-Feed: Fuel enters from the in the top and exits the bottom.


Side-Feed: Fuel enters on the side on the injector fitting inside the fuel rail.


Throttle Body Injectors: Located directly in the throttle body.
