High Pressure Accumulator (Common Rail)
Description
The high pressure accumulator reserves the high pressure fuel. Simultaneously, the pressure changes due to the
delivery from HP pump and the fuel injection is diminished by rail volume. This high pressure accumulator is commonly
used in all cylinders. Even when a large amount of fuel leaks, the common rail maintains its internal pressure. This
ensures that the injection pressure can be maintained from when the injector opens.
Function
• Relieve the pressure pulsation
• Provide pressure information to ECU (fuel pressure sensor)

High Fuel Pressure Pipe
• Function: Resistant to pressure changes, tightness against surroundings, supplying fuel through pump, rail and
injector with high pressure
• Material: Steel (Zn Plated)
• Common: Cylinder 1 & 3, 2 & 4, 5
• Internal pressure
- Internal operating pressure: 0 ~ 1600 bar during its lifetime
- Spontaneous max. pressure when restoring: 2100 bar (max. total period: 20 hours)
- Bursting pressure: over 2500 bar
• To keep cleanness and tightness, the high pressure pipe assembly should be used only once.
