Fuel injectors are the components that are responsible for the final stage of fuel delivery in fuel injection systems. High pressure fuel is delivered to the injector, which is activated by an engine control unit or fuel injector control module. When activated, the injector momentarily opens a valve that allows a precise amount of fuel to spray out.
Although a fuel injection system may have a single injector (i.e. central-point injection) or several (i.e. multiport injection), and injectors vary somewhat in design from one application to another, they all perform that same basic function.
