Fuel injector 095000 0562

Principle of Fuel Injector:
High pressure is generated in the injector body to act on the conical surface of the injector. When the oil pressure exceeds the setting value, the spool of the injector is opened, and the high pressure oil is ejected from the orifice of the nozzle and burns in the engine cylinder in a mist shape, so that the piston runs reciprocally. More information is as follows:
1. The injector is a precision device with very high machining accuracy, which requires a large dynamic flow range, strong resistance to blockage and pollution, and good atomization performance. The injector receives the fuel injection pulse signal sent by the ECU to accurately control the fuel injection amount. The spray characteristics of the injector include atomization particle size, oil spray distribution, oil beam direction, range and diffusion cone Angle. These characteristics should MEET the requirements of diesel engine combustion system to make the mixture formation and combustion perfect, and obtain higher power and thermal efficiency.
2. The electronically controlled fuel injector is the most critical and complex part in the common rail system, as well as the most difficult part in the design and process. By controlling the opening and closing of the solenoid valve, the ECU will inject the fuel in the high-pressure oil rail into the combustion chamber with the best injection timing, injection volume and injection rate. In order to achieve effective fuel injection starting point and accurate fuel injection volume, the common rail system uses hydraulic servo system and electronic control components.
