What is a fuel injector composed of?
1 Answers
A fuel injector consists of three parts: the fuel supply section, the air supply section, and the control section. Below is extended information about fuel injectors: 1. The fuel supply section is composed of the fuel tank, fuel pump, fuel filter, pressure regulator, and fuel injector. 2. The fuel pump draws gasoline from the fuel tank, filters impurities through the fuel filter, pressurizes the gasoline via the pressure regulator to ensure the fuel pressure is higher than the negative pressure of the intake manifold, and then delivers it to each cylinder's injector through the fuel line. 3. The injector functions like a switch, with the control component being the ECU. The injector is controlled by an electromagnetic coil, and the on-off current of the electromagnetic coil is regulated by the ECU.
