The Principle and Detection of Electromagnetic Fuel Injector

The fuel injector is an important part of the engine fuel system. With the popularization of electronic control technology, the fuel injection of automobiles, engineering vehicles, and agricultural vehicles has begun to be electronically controlled.
The structure of the injector
Injector It is a solenoid valve, controlled by the engine control unit. Gasoline under the pressure of the oil distribution pipe enters the fuel injector, and the needle valve is closed under the force of the return spring, and the fuel injector cannot inject fuel: when the ECU controls the electromagnetic coil of the injector to be energized, the magnetic field generated by the electromagnetic coil drives the armature, The needle valve moves up, the needle valve opens, and the fuel injector injects fuel. Generally, the lift of the needle valve of the injector is about 0.lmmo
2 Basic principle of injector
The principle of the fuel injector control circuit is shown in Figure 1. The electromagnetic coil of the fuel injector leads to two wires, one wire is the power supply, which supplies 12V voltage after the ignition key is turned on, and the other wire is the ground circuit controlled by the electronic control unit. When the fuel injector needs to open the fuel injection, the electronic control unit ECU controls the grounding of this line through the triode, and the electric current flows through the electromagnetic coil, and the fuel injector opens the fuel injection. Each time the ECU controls the magnetic flux of the injector electromagnetic wire is called the fuel injection pulse width, which is in the range of 2~10ms.
