Gasoline cars have fuel injectors, and the relevant introduction to fuel injectors is as follows. Definition of Fuel Injector: A fuel injector itself is a normally closed valve (a normally closed valve means that when there is no input control signal, the valve remains closed; whereas a normally open valve remains open when there is no input control signal), controlled by the up and down movement of a valve needle to open or close the valve. When the ECU issues a fuel injection command, its voltage signal causes current to flow through the coil inside the fuel injector, generating a magnetic field that lifts the valve needle, opening the valve to allow fuel to spray out from the injector nozzle. Function of Fuel Injector: As one of the key components of an electronic fuel injection engine, the performance of the fuel injector significantly affects the engine's overall performance. A clogged fuel injector can severely impair the car's performance. The clogging is usually caused by carbon deposits accumulating on the injector or impurities in the fuel blocking the injector's pathways. After a period of driving, certain deposits will form in the fuel system.
