The fuel injector is a precision device with very high machining accuracy, which requires a large dynamic flow range, strong anti clogging and anti pollution capabilities, and good atomization performance. The fuel injector receives the injection pulse signal sent by the ECU and accurately controls the fuel injection amount. The spray characteristics of the fuel injector include atomization particle size, fuel spray distribution, fuel spray direction, range and diffusion cone angle. These characteristics should meet the requirements of the diesel engine combustion system to achieve perfect mixture formation and combustion, as well as high power and thermal efficiency. The fuel injector is composed of a hole type fuel injector similar to traditional fuel injectors, a hydraulic servo system (control piston, control orifice, etc.), a solenoid valve, etc
