Fuel injector nozzle is a very high precision machining precision devices, requiring large dynamic flow range, strong anti-pollution and anti-clogging and good atomization performance. Injector ECU works receiving the pulse signal sent from the injection, accurate control of fuel injection amount.
Fuel injector nozzle and injector nozzle which is mainly composed of body composition, it depends on the design of the combustion chamber in the installation position and angle of the cylinder head.
Fuel injector spray characteristics include atomization, mist distribution, oil beam direction, range and diffusion cone angle. These characteristics should meet the requirements of diesel engine combustion systems to make perfect mixture formation and combustion, and to obtain a higher power and thermal efficiency. Injector is divided into open and closed two. Simple injector open structure, but poor atomization, are rarely used. Closed injectors widely used in a variety of diesel engines.
