GENERAL
The TdV6 is equipped with a High-Pressure (HP) common rail fuel injection system. With this fuel injection process, a
High-Pressure Pump (HPP) delivers a uniform level of pressure to the shared fuel lines (the common rails), which serve
all six fuel injectors. Pressure is controllable, to the optimum level for smooth operation, up to 1650 bar.
The common rail system supports a pre-injection (pilot) phase, which reduces combustion noise and mechanical load.
Fuel injection pressure is generated independently of engine speed and fuel injection events.
The fuel injection timing and volume are calculated by the Engine Control Module (ECM), which then energizes the
