Carburetors rely on vacuum and mechanical principles to mix air and fuel, a process that is inherently less precise and more susceptible to environmental changes. Another configuration is Throttle Body Injection (TBI), which resembles a traditional carburetor by placing one or two injectors in the throttle body.

Other vital sensors track engine speed (crankshaft position sensor), coolant temperature, oxygen levels in the exhaust, and throttle plate position, providing a constant stream of data to the central processing unit. This setup provides a highly uniform air-fuel mixture for optimal combustion.
Furthermore, an ignition control module works in tandem with the ECU to determine the exact moment a spark plug should fire, ensuring the air-fuel mixture is ignited for maximum power. Core Components of an EFI System The functionality of an EFI system relies on a coordinated interplay between hardware and software.

The ECU processes this information incredibly quickly, often hundreds of times per second. The most common configuration is Multi-Point Fuel Injection (MPFI), where a separate injector is installed directly near the intake valve of each cylinder.
