The task of common rail pipe is to store high-pressure fuel, and the pressure fluctuations generated by fuel supply and injection of high-pressure pump are buffered by the volume of common rail pipe. When outputting a large amount of fuel, the common rail pressure shared by all cylinders should also be kept constant to ensure that the injection pressure remains invariable when the fuel injector is opened.

The common rail is equipped with a common rail pressure sensor and pressure limiting valve, and a flow limiter. Common rail pipes with flow limiters (optional), pressure sensors, pressure regulating and limiting valves can be designed differently owing to the different installation conditions of diesel engines.

The pipe is usually filled with high-pressure fuel, fully utilizing the compression of high-pressure fuel to maintain storage pressure, and a high-pressure pump is used to compensate for pressure fluctuations caused by pulsating fuel supply. Therefore, the pressure inside the common rail pipe is approximately constant even if fuel is injected from it.
