[0002] The high-pressure fuel rail is a crucial component of the high-pressure common rail fuel injection system of modern diesel engines. It is a pipeline that stores high-pressure fuel, located on the engine, and connects the high-pressure fuel pump and individual injectors. The pressure within the rail is precisely controlled by an electronic control unit based on the engine's operating status to ensure that the injectors spray the appropriate amount of fuel at the correct time and pressure. During the manufacture and assembly of the high-pressure rail, a dedicated press-fit device is used to ensure the precise installation of the rail and its accessories. However, existing devices are generally installed manually or by clamping for quick connection. While this installation method improves installation convenience to a certain extent, it lacks flexibility and is difficult to adapt to different mounting holes.
