Common Rail
The common rail stores the pressure of the HPP and supplies the
injectors with fuel. The sensor and the pressure control valve are
fit in the common rail.
The high pressure accumulator is common to all cylinders. Its
available rail volume is permanently filled with pressurized fuel.
The compressibility of the fuel resulting from the high pressure is
utilized to achieve the accumulator effect. This causes a
practically constant rail pressure even when fuel leaves the rail
for injection. See Figure 4.
