What are the components of an electronically controlled fuel injection system?
1 Answers
An electronically controlled fuel injection system consists of the following three subsystems: the fuel supply system, the intake system, and the electronic control system. 1. Fuel Supply System: The fuel supply system is composed of the fuel tank, fuel pump, fuel filter, pressure regulator, pulsation damper, fuel injector, as well as fuel supply lines and return lines (travel car rental). 2. Intake System: The intake system includes the air filter, throttle valve, air flow meter, intake chamber, idle control valve, and intake control valve. The functions of the fuel supply system and intake system are to mix the fuel injection quantity and intake air quantity determined by the ECM/ECU based on the throttle position (engine load) and engine speed into a combustible mixture, which enters the cylinder for combustion and power generation. 3. Electronic Control System: The electronic control system consists of several sensors that detect various engine conditions, an ECU that determines the fuel injection quantity based on sensor signals, and fuel injectors that operate according to ECU commands. Its main function is to determine the optimal fuel injection timing and duration based on different engine operating conditions.
