What does "EFI" mean? EFI is the abbreviation for electronic fuel injection system in automobiles, and its full spelling is electric fuel injection. EFI， Scalable Firmware Interface, also known as Extended Firmware Interface, is an upgrade solution introduced by Intel, a leading company in personal computer technology research and development, to replace BIOS in future PC like computer systems. At the same time, EFI is also an abbreviation for electronic fuel injection (system), which is a system that uses various sensors to detect the various states of the engine. Through computer judgment and calculation, the engine can obtain a suitable concentration of combustible mixture under different operating conditions. The concept of electronic fuel injection (EFI) is the working principle of electronic fuel injection (system). The electronic gasoline injection system uses various sensors to detect the various states of the engine, and through computer judgment and calculation, the engine can obtain a suitable concentration of combustible mixture under different operating conditions. The electronic control fuel injection system detects the engine intake air volume through an air flow meter, manifold absolute pressure sensor, or throttle position sensor. The electronic control unit Hongsi Liang judges, calculates, and corrects the duration of fuel injection by the fuel injector based on the signals from various sensors, so that the engine can obtain the optimal combustible mixture concentration required for operation under this condition. The electronic gasoline injection system consists of four parts: intake system, fuel system, ignition system, and control system. The intake system provides the necessary air for the formation of the engines combustible mixture. The air enters the cylinder through the air filter, air flow meter, throttle body, intake manifold, and intake manifold. In the fuel system, gasoline in the fuel tank is pumped out from the fuel pump, flows through the gasoline filter to the fuel injector, and in a multi-point injection system, the injection pressure is generally within the range of 2 to 5.5 bar when it is above 2 bar; The pressure of the single point injection system is 0.7~1.2 bar. The excess fuel flows back to the fuel tank through the pressure regulator. The fuel injection quantity is controlled by the duration of the fuel injectors power on time. The ignition timing signal generated by the electronic control unit is sent to the igniter, which connects and disconnects the primary circuit of the ignition coil, causing the spark plug to ignite. At the same time, the igniter feeds back an ignition confirmation signal to the electronic control unit. The control system consists of sensors, electronic control units, and actuators. Its core is the electronic control unit. The electronic control unit calculates the intake air quantity through the absolute pressure sensor of the intake manifold or the signal of the air flow meter, and obtains the basic fuel injection duration and basic ignition advance angle based on the intake air quantity and the engine speed. Then, it corrects various working parameters such as cold water temperature, intake shielding width temperature, throttle opening angle, battery voltage, etc., to obtain the optimal fuel injection duration or optimal ignition advance angle for the engine to operate under this condition. According to the requirements of the engine, the electronic control unit ca
