Electronically controlled gasoline injection system definition
The electronically controlled gasoline injection system (EFI system) is based on the electronic control unit (ECU), and uses various sensors installed on the engine to measure various operating parameters of the engine, and then accurately according to the pre-stored control program in the computer. Control the fuel injection amount of the injector so that the engine can obtain the best air-fuel ratio combustible mixture under various working conditions. At present, the electronically controlled gasoline injection systems used in various types of automobiles often have large differences in structure, and each has its own characteristics in terms of control principles and working processes.
