Fuel injector is a device that injects fuel into the cylinder of an engine. In fact, when the solenoid valve is opened, the nozzle can generate enough fuel injection force.
The injector itself is a normally closed valve (normally closed valve means that when there is no input control signal, the valve is always in the closed state; while the normally open valve means that when there is no input control signal, the valve is always in the open state, and the opening and closing of the valve is controlled by a valve needle moving up and down. When the ECU sends the fuel injection command, its voltage signal will make the current flow through the coil in the fuel injection nozzle, which will generate a magnetic field to suck up the valve needle and open the valve so that the oil can be ejected from the injection hole. The biggest advantage of injection fuel supply is that the control of fuel supply is very accurate, so that the engine can have the correct air-fuel ratio in any state. Not only can the engine keep running smoothly, but also its exhaust gas can meet the requirements of environmental protection laws and regulations.
