[0002] In the automotive manufacturing industry, the common rail system is a crucial component of the high-pressure common rail system in diesel engines. The common rail pipe itself is a vital part of the high-pressure fuel injection system, requiring precise positioning and dimensional accuracy within the engine. The primary step is to precision machine the positioning holes on the rail body using the outer diameter as a reference. Then, the high-pressure fuel inlet and outer diameter threads are precision machined using these positioning holes. Only in this way can the dimensional accuracy of the various holes in the common rail pipe body be guaranteed.
