高压油管是燃油系统的重要零件之一,它起着连通喷油泵和喷油器的作用。工作时承受很高的燃油压力。由于燃油在喷射过程中,高压油管内产生极其复杂的液力过程,油管锥头孔径对柴油机的工作有明显的影响。但是在燃油系的检修中。人们往往只重视对喷油泵及喷油器的修理,而对高压油管一般都是在锥头压不住时才给予更换。由于反复装卸引起锥孔缩变所造成的影响,却往往被人们忽视。我们多次发现,将调试好的喷油泵和喷油器装到发动机上,不一
High-pressure fuel pipe is one of the important parts of the fuel system, which plays a role in connecting the fuel injection pump and injector. Work under high fuel pressure. Due to the fuel injection process, the high-pressure tubing produces extremely complex hydraulic process, the pipe taper aperture has a significant impact on the work of the diesel engine. But in the fuel system maintenance. People tend to focus only on the injection pump and injector repair, and the high-pressure tubing are generally available in the conical pressure could not be replaced. Due to the repeated loading and unloading caused by the tapered hole caused by the impact, but often overlooked. We have found many times that different modified fuel injectors and injectors are installed on the engine
