Diesel engine fuel injector is one of the precision parts, and the gap between the needle valve and needle valve only 0.002 ~ 0.003 mm. Nozzle in the shape of the fuel system is a very important parameter, the spray quality, injection, in the form of fuel and air mixing state has a great influence of these factors directly affect the diesel engine emissions targets. In recent years, in order to meet the requirements of increasingly stringent diesel engine exhaust emissions, achieve better economic performance and emission performance, the fuel injector is as follows: 
Syringe will be some pressure atomized diesel oil into small particles evenly, make the diesel engine combustion chamber and air mixture. Nozzle structure parameters of nozzle hole number, diameter, taper Angle, and it is at the top of the combustion chamber, direct exposure to high temperature and high pressure gas mixture, high operating temperature, working condition. Heat load and mechanical load is often caused by poor needle valve sealing, gas channel, and stop work, in addition, the work condition of the fuel injector is good or bad, will directly affect the economic power of diesel engine, emission and reliability.
