The electronic fuel injection (EFI) fuel delivery system precisely meters fuel to engine cylinders according to demand.
Instead of carburetors, EFI employs sensors, an electronic control unit (ECU), and injectors for exact fuel regulation.
Sensors continuously measure engine conditions such as air intake, temperature, throttle position, and RPM.
The ECU interprets this sensor data to command injectors, ensuring optimal fuel delivery across varied driving scenarios.
Fuel is injected under high pressure directly into intake ports or combustion chambers, promoting superior air-fuel mixture.
This results in enhanced fuel economy, greater power, and lower emissions.
In summary, EFI fuel delivery systems offer automated, precise fuel control for peak engine performance.
