In an electronic fuel injection system, the amount of fuel required by the engine is provided by injectors controlled by the ECU. The Electronic Control Unit (ECU) performs calculations necessary for optimizing fuel supply and ignition timing based on information provided by various sensors, including intake air temperature and cylinder temperature sensors, crankshaft position sensor, atmospheric pressure and manifold pressure sensors, as well as throttle position sensor. The EFI system can maintain the air-fuel ratio required for the engine to operate efficiently according to working conditions and engine requirements.

Advantages of Electronic Fuel Injection (EFI):

Lower fuel consumption

Electronic fuel injection systems have lower fuel consumption compared to carburetor engines. This is due to the precise electronic control system, which continuously calculates and adjusts the air/fuel ratio to maintain ideal combustion conditions. Smaller carburetors tend to make the engine mixture too rich (overfuelled) at both low and high power outputs. Carburetors are particularly inefficient when used under continuously changing conditions because it is difficult to set the ideal air-fuel ratio for all throttle opening positions. Effective altitude compensation is difficult to achieve with carburetors, whereas it is built into the system and works seamlessly with electronic fuel injection. Although the reduction in fuel consumption varies depending on the engine and various conditions, it can be reduced by 5% to 25% compared to carburetor engines.

Greater power

Engines equipped with electronic fuel injection systems usually provide higher power and torque than the same engine's carburetor version. At lower engine speeds
