Diesel injectors are generally divided into two types: open type and closed type. However, due to various disadvantages such as simple structure and poor fuel atomization of open type injectors, they are rarely used now. Closed injectors are widely used at present. Closed injectors are further divided into orifice injectors, pintle injectors and low inertia injectors according to the structure of the injectors. These are also the most common types of injectors, which are used for different used in diesel engines.
The orifice injector is mainly composed of needle valve, needle valve body, ejector rod, pressure regulating spring, pressure regulating screw and injector body  the main parts are needle valve and needle valve body, which are the main components of diesel engine. One of the three precision couplings, which is also the main type of research in this paper. At the same time, the orifice injector is divided into long and short. The needle valve guide cylinder of the short orifice injector is closer to the combustion chamber. Compared with the long orifice injector, the needle valve is heated more. It is easy to deform and cause faults such as jamming, so it is mostly used in diesel engines with small thermal loads. The fuel injector is mainly composed of electromagnet, solenoid valve spring, armature, valve stem, isolation block, ball valve, intermediate block, metering hole, sleeve, needle valve, needle valve spring, nozzle, sleeve and inner sleeve.
