What does Electronic Fuel Injection (EFI) refer to?

Electronic Fuel Injection (EFI) refers to a sophisticated method of introducing fuel into internal combustion engines. This process is meticulously controlled by an engine control unit (ECU), which optimizes fuel delivery based on various inputs such as engine temperature, air intake, and throttle position. EFI systems replace traditional carburetors and improve engine efficiency, performance, and emissions control.

The ECU continuously monitors and adjusts the fuel-air mixture, ensuring that the engine operates efficiently under varying conditions. This precise control allows for improved power output and reduced fuel consumption, making EFI a popular choice in modern engines. Through advanced sensors and computer algorithms, EFI provides a significant advantage over older fuel delivery systems.
