Electronic Fuel Injection (EFI): Overview and Benefits
How EFI Works: EFI is a modern fuel delivery system for internal combustion engines, replacing the older carburetor system. It uses electronically controlled fuel injectors to precisely inject fuel into the intake manifold or cylinder, optimizing the engine's performance.
Fuel Pump: Delivers fuel to the fuel rail.
Fuel Injectors: Inject fuel directly into the engine in precise amounts.
Engine Control Unit (ECU): Controls the fuel injectors, adjusting fuel delivery based on input from various sensors.
Sensors: Measure factors like air flow, engine speed, and oxygen levels, providing critical data to the ECU for fine-tuning fuel delivery.
Advantages of EFI:
Improved Fuel Economy: By delivering fuel more efficiently, EFI reduces fuel consumption.
Increased Power: More accurate fuel delivery enhances engine power and performance.
Reduced Emissions: Cleaner fuel combustion leads to lower exhaust emissions.
Better Startability: EFI systems help engines start more easily in a variety of conditions.
Enhanced Drivability: EFI improves throttle response and provides smoother, more predictable engine performance.
