INJECTOR KNOWLEDGE

The basic mission of the diesel fuel injection system is to inject the precise amount of fuel into the combustion chamber at the correct injection timing and the set injection pressure in each cycle according to the power output of the diesel engine. The fuel injection system has a very important impact on the power performance, economical emission and NVH of the diesel engine. As the key core component of the diesel fuel system, the fuel injector has high processing and assembly precision. Once a failure occurs, it is difficult to repair it by replacing parts. Therefore, reasonable structural design, good processing accuracy, suitable surface treatment and accurate assembly indispensable. The design, processing and surface treatment of fuel injectors are generally controlled by mature professional suppliers. For OEMs. Its installation structure, especially the fixing method, plays a vital role in the normal operation of diesel engines.

In order to ensure the reliable operation of the engine, there are strict requirements on the installation and fixation of the injector. The fuel injector is generally fixed on the engine cylinder head through the pressure plate and its fastening bolts. The key points are: ensure the positioning of the fuel injector, avoid movement and rotation; ensure the fastening and sealing of the fuel injector, and provide enough fuel for the fuel injector. The axial pretightening force ensures that the high-temperature and high-pressure gas in the combustion chamber will not leak from the injector hole of the cylinder head to limit the vibration of the injector. Avoid accidental wear and circuit, oil circuit seal failure.
