What is the function of an electronically controlled fuel injection system?

[AnnaFitz]

The function of an electronically controlled fuel injection system is to precisely control the fuel injection quantity, injection timing, and injection pressure, ensuring that the fuel injected into the engine cylinders achieves optimal performance, resulting in improved power, fuel economy, and emissions. The application of electronic fuel injection systems makes precise and flexible engine control possible, realizing the dream of direct-injection gasoline engines and achieving lean combustion. Advantages of electronically controlled fuel injection systems: 1. Improved engine power, fuel economy, and exhaust emission performance; 2. Air-fuel ratio feedback control reduces emissions; 3. Fuel is directly injected into the intake manifold, ensuring uniform mixture distribution among cylinders; 4. Precise control of ignition timing allows for more complete combustion of the air-fuel mixture, meeting the requirements of various engine loads; 5. Features self-diagnostic capabilities, making it easier for users to inspect and maintain.
