Electronic Fuel Injection (EFI) is a system used in modern vehicles to deliver fuel to the engine. Unlike older carburetor systems, EFI uses electronic sensors and computer controls to precisely manage the amount of fuel injected into the combustion chamber. This helps improve fuel efficiency, reduce emissions, and enhance engine performance. The EFI system monitors various factors, such as engine temperature and air intake, to adjust the fuel mixture accordingly. By optimizing the fuel delivery, EFI ensures that the engine runs smoothly and efficiently under different driving conditions. This technology has become standard in most vehicles today, contributing to better overall performance.
